    ME 414 THERMAL-FLUID SYSTEMS DESIGN COURSE

    ME 414 is a thermal-fluid systems design course in which the students learn about the design of piping systems and heat exchangers beyond the last thermal-fluid course (ME 314 Heat and Mass Transfer) they take before or simultaneously with this course. As a part of the course, the students work in teams to design products with piping systems and heat exchangers. They present their work orally to a jury of faculty and industry representatives. They also write design reports describing their work and consider functionality and manufacturability of their designs as well as the economical, environmental, and safety aspects of their design (see Syllabus and Course Outcomes for more information).

    All reports are expected to meet professional standards (see Report Format). Moreover, a formal assessment form is used by the jury to evaluate the projects (see Assessment Form).

    The course materials and presentations of student projects of recent years may be accessed from the following list:

    As an engineer, specifying heat exchangers for procurement is an important step in the successful execution of any heat transfer or energy conservation project. Early recognition that there are many different heat transfer technologies available can help in receiving optimized bids for each type of equipment available to you. Through process investigation, the specifying engineer can collect the necessary data to allow the heat exchanger designer to optimize both the mechanical and thermodynamic design of the heat exchanger. Through the specification process, you can uncover critical variables such solids loading, heat transfer duty requirements, available footprint space, maintenance considerations, and others.

    Design
    Chart Energy & Chemicals' heat exchangers owe their inherent versatility and high-performance characteristics to the advanced design technology and construction of the plate-fin matrix.
    Individually constructed in aluminum, each heat exchanger is built by stacking layers of corrugated fins separated by parting sheets and sealed along the edges with side bars.
    The matrix assembly is brazed in a vacuum furnace to form an integral, rigid heat exchanger block. Headers and supports welded onto the brazed matrix complete the unit.
    Process Design
    Chart Energy & Chemicals has developed a comprehensive range of heat transfer fins with a proven design for every application. Design variations in the configuration of the heat exchanger matrix can accommodate an almost unlimited range of flow options, including counterflow, crossflow, parallel flow, multi-pass and multi-stream formats.
    Chart E&C's process engineers have a wealth of experience and test data to use in selecting the most appropriate heat transfer fin for the customer’s individual requirements.
    The herringbone and serrated fins provide the greatest surface area and the highest heat transfer performance. They are particularly suitable for applications involving close temperature approaches. Where there are critical pressure drop requirements, the plain and perforated fins can be used.

    PLAIN
    A sheet of metal with corrugated fins at right angles to the plates.
    PERFORATED
    A plain fin constructed from perforated material.

    HERRINGBONE
    Made by displacing the fins sideways at regular intervals to produce a zig-zag effect.
    SERRATED
    Made by simultaneously folding and cutting alternative sections of fins. These fins are also known as the lanced or multi-entry pattern.

    Chart E&C process engineers are able to enhance standard flow patterns, i.e. crossflow and counterflow, into more compact configurations.
    A simple crossflow layout is generally suitable for low to moderate duties. It is used extensively for gas / liquid applications and is especially effective when handling a low-pressure gas stream on one side of the heat exchanger. For heavier duty tasks, where the mean effective temperature difference in crossflow may be significantly reduced, the compact counterflow pattern frequently offers an efficient solution.
    The higher levels of efficiency achieved by counterflow units are essential to most low-temperature applications. Headering arrangements must, of course, be matched to the customer’s process requirements.
    Mechanical Design
    On both sides of the Atlantic, Chart Energy & Chemical's engineering teams combine a wealth of experience with the latest state-of-the-art engineering and design programs. Together they provide an industry-leading design capability that has the range and flexibility to meet specific customer needs anywhere in the world.
    Research and development programs are dedicated to the goal of enhancing international "best practice" procedures. Whatever the location, customers benefit from a design philosophy shaping the future of advanced plate-fin heat exchanger applications.
    Design Codes
    Backed with more than 50 years' hands-on experience with multi-national pressure vessel codes and inspection regulations, Chart Energy & Chemicals has gained world-wide recognition for its expertise in all aspects of plate-fin heat exchanger technology.
    Advanced PC-based procedures for thermal, hydraulic and mechanical design add a new dimension to an already established world class product and for any international requirement.
    Chart E&C's heat exchangers are designed primarily according to ASME VIII code requirements and marked with the “U” compliance stamp. Nevertheless, Chart Energy & Chemicals is fully conversant with a multitude of international code requirements ensuring a truly global reach.

    Air Products is the largest supplier of baseload LNG heat exchangers in the world. Over 70 of these large exchangers have been produced or are being fabricated currently at our manufacturing plant in Wilkes-Barre, Pennsylvania. The expertise developed over the years, covering all phases of design, manufacture, and inspection remains in place to benefit future LNG projects. Air Products has more than 40 years experience in the design and fabrication of aluminum wound coil heat exchangers, starting with exchangers built for helium recovery in the early 1960's.
    Design
    Thorough and well tested process and mechanical designs for the MCR® Cryogenic Heat Exchangers are the major factors leading to successful operation and flexibility of the process cycle. The heat transfer process is complex, with heat being transferred from a single refrigerant warming stream to several cooling streams. Since each stream consists of a mixture of components and usually occurs as mixed liquid and gas phases, heat transfer is influenced by the mass transfer between phases, and both are affected by pressure drop. The use of a multicomponent refrigerant permits optimization of MCR® Cryogenic Heat Exchanger cooling curves as well as ensuring that much of the heat exchange occurs in the high coefficient, two-phase region. In addition, for this type of heat exchanger, the tube circuit areas can be accurately matched to tube circuit heat duties. Theoretical analyses by means of mathematical models and the extensive data collected from various operating facilities have been incorporated into Air Products' MCR® Cryogenic Heat Exchanger. Air Products' process design coupled with mechanical designs for obtaining proper distribution in two-phase flow, have led to outstanding exchanger performance at each plant.


    Features
    The employment of Air Products' MCR® Cryogenic Heat Exchangers has the following advantages:
    • The capability to design and fabricate very large heat exchangers, up to 16.5 feet in diameter, facilitates the construction of large process trains, which are limited only by the availability of large proven compressors and drivers. In addition to achieving economies of scale, this leads to simplified piping and control systems and, consequently, to reductions in installation, operation, and maintenance costs.
    • Long service life and minimal downtime are achieved by virtue of the innovative design and mechanical construction of Air Products' MCR® Cryogenic Heat Exchangers.
    • Maximum preassembly of equipment can be facilitated by the package design concept, utilizing common pipe and platform support points on the exchanger shell. This leads to substantial reduction in field erection time and cost.
    • Reduced field erection and other capital costs and have resulted from designs that include internal separators, piping manifolded inside the heat exchanger shell to reduce the external piping and integral lifting lugs on the external shell.
    • The use of multiple tube circuit exchangers eliminates the need for precise shell-side flow distribution between parallel, single-circuit exchangers.
    • Higher operating pressures on the condensing side of the exchanger are made possible by the use of small bore aluminum tubing. This permits utilization of high-pressure feed gas and optimization of the mixed refrigerant pressure for higher process efficiency. The small tubing also permits construction of a compact exchanger incorporating a large amount of heat transfer surface. Thus, the process can be designed with small temperature differences and reduced compressor energy requirements.
    • The use of higher pressure exchanger shells conserves refrigerants when the liquefaction plant is shut down by permitting a rise in shell pressure to three or more times the normal operating pressure. In addition to the basic economic benefit, refrigerant containment is particularly significant for marine liquefaction facilities and for sites where refrigerant importation is required.
    • Reduced maintenance time is provided by easy access to all tubesheets through seal welded handholes that are accessible from outside the exchanger shell
