文摘

The heat exchanger performance has a nonlinear variation under low pressure. The boundary layer is the main cause for the change of heat exchanger performance. Heat boundary layer is inflected by pressure in both dynamic and steady states. The pressure drop is help to improve the air-side field synergy of finned tube.
