详细说明了换热器模型在FLUENT中是使用方法。(In a typical heat exchanger core, the auxillary fluid temperature is stratied in the direction of the auxillary fluid flow. As a result, heat rejection is not constant over the entire core. In ANSYS FLUENT the fluid zone representing the heat exchanger core is subdivided into macroscopic cells or macros along the auxillary fluid path. The auxillary fluid inlet temperature to each macro is computed and subsequently used to compute the heat rejection from each macro. This approach provided a realistic heat rejection distribution over the heat exchanger core.)
