Sažetak
Abstract: Plate type heat exchangers are commonly used in marine industry due to their favorable characteristics vs. shell and tube heat exchangers, such as smaller volume for similar heat exchange rates. The manifold design is optimized in this work via computational fluid dynamics (CFD) analysis to result in uniform flow distribution along the entire flow field. Different manifold configurations are compared in terms of pressure drop and velocity profiles along the flow field cross-section for two different manifold inlets – longitudinal and transverse, in respect to the flow channels. Several designs are compared for one single-cell in terms of heat exchange capacity for a fixed external geometry frame. Performance is compared for the optimal manifold geometry for different mass flow rates of the cooling fluid. The objective of the study is to design compact heat exchanger with simple flow field geometry for the prescribed outlet temperature of the hot fluid.
