The compact flow heat exchangers are important components of the equipment for power generation, chemical processing, and thermal environment control. This paper presents the flow pattern characterization and heat transfer performance for two-phase compact and ultra-compact heat exchangers. The scaling analysis is presented in this paper to identify the effect of various forces. The heat transfer enhancement mechanisms during flow boiling and condensation in compact heat exchangers are discussed using experimental data for refrigerant R-21. The mechanisms of subcooled and saturated flow boiling in ultra-compact heat exchangers based on microchannels are discussed using experimental data obtained for water.
