Compact Heat Exchangers have been recognized in aerospace, gas turbine power plants, automobiles and other industries for over half a century. Factors such as energy consumption, size constraints, fluid corrosiveness, high performance requirements, lower fluid inventory and the use of a gas as one of the fluids in the Heat Exchanger have contributed to the attractiveness of the Compact Heat Exchanger over the years. While there is extensive literature on Heat Exchangers, comprehensive theoretical design information on Compact Heat Exchangers is not extensively available. Consequently, systematic treatment of many aspects of compact heat exchangers and specifically Printed Circuit Heat Exchangers (PCHE) is unavailable. Conventional methods for Heat Exchanger design utilize commercial codes for their analysis due to the complexity of the iterative nature of typical heat exchanger design processes. This thesis congregates ideas and industrial concepts related to heat exchanger design to provide a systematic treatment of the sizing and ratings concerns encountered during the design of Printed Circuit Heat Exchangers for the heat exchange systems in a conceptual Molten Salt Breeder Reactor (MSBR) design known as the Liquid Fluoride Reactor. The Liquid Fluoride Reactor is a 165.7 MWth reactor that utilizes three heat exchangers that use molten salts and Helium gas as the heat transport fluids. The work presented herein recommends a design procedure that is based on the thermal and transport properties of the heat exchanger fluids, the operating conditions, heat exchanger material, surface properties of the heat exchanger, and exposes some of the limits of conventional methods in the Printed Circuit Heat Exchanger design due to an unavailability of empirical heat transfer and pressure drop correlations. In addition to revealing the extent of the design criteria that needs to be defined, the work presented also provides support to the importance of implementing application-specific heat transfer and pressure drop correlations during the design stages if the goal is to recommend a prescriptive design. The fluids used in the design algorithm are specific to the LFR but the systematic deduction of solutions to the problems of sizing and rating are transferable to other Printed Circuit Heat Exchanger Design Applications.
