Flow maldistribution in heat exchangers
WebMultipassage heat exchangers are normally designed with the assumption that the fluid stream is uniformly divided among all the parallel channels. But, in practice, an improper entrance configuration or imperfect flow passages create a flow maldistribution. Paired-channel exchangers in which the channels are continuously distributed as a function of … WebJul 23, 2024 · Multiphase flow phenomena in single micro and minichannels have been widely studied. Characteristics of two-phase flow through a large array of microchannels are investigated here. An air–water mixture is used to represent the two phases flowing through a microchannel array representative of those employed in practical applications. Flow …

In this work, 16 tubes are connected between the inlet and the exit headers forming the heat exchanger. The feed…. WebIt may incorporate cross-flow, counter-flow, or co-current flow. Typically heat exchangers utilize combinations of these flow patterns to maximize thermal efficiency. In single pass heat exchangers, fluids flow by each other only once in the system. Fluids in multi-pass heat exchangers are looped back to flow by each other multiple times.
