Обобщенное уравнение для расчета гидравлического сопротивления каналов пластинчатых теплообменников

Abstract

The paper concerns with analysis of the influence of corrugation form of plate heat exchangers (PHEs) heat transfer plates on hydraulic resistance of the formed channels. The crucial influence of the corrugation inclination angle to the vertical axis of plate is shown. The equation, which generalizes experimental data of different authors for hydraulic performance of inter-plate channels with sinusoidal and triangle corrugations shape is obtained. The equation can be used for calculations at the PHE plate corrugation patterns optimization.
