Recent Research and Developments in Plate Heat Exchangers

TLDR

The paper focuses on designing plate heat exchangers for single‑phase, evaporation, and condensation processes. The study models plate heat exchanger design, analyzes flow patterns for local heat transfer and velocity fields, and correlates two‑phase heat transfer coefficients and pressure drops with smooth‑tube models. Results show the thermal and hydraulic performance of corrugated channels in single‑phase flow, and the authors propose recommendations for future research.

Abstract

This paper deals with the design of plate heat exchangers for processes in single-phase, evaporation and condensation. Some results are given for the thermal and hydraulic performance of corrugated channels in single phase flow. The flow pattern is analysed to give some local information on the heat transfer and the velocity field. In two phase flows, the heat transfer coefficient and the pressure drop are correlated with models originally developed for smooth tubes. Some recommendations are proposed for future research.
