Keywords: Chevron; Corrugation; Plate heat exchanger; L This paper introduces a simple and reliable iterative procedure for estimating cold ( $$T_{\text{co}}$$ ) and hot ( $$T_{\text{ho}}$$ ) fluid outlet temperatures in a Chevron plate Manufacturers of plate and frame heat exchangers nowadays mainly offer plates with chevron (or herringbone) corrugation patterns. Experiments were performed to investigate steady state heat transfer and pressure drop in a plate heat exchanger. In this paper, an experimental setup for testing a chevron type brazed plate heat exchanger is Plate heat exchangers (PHEs) have been widely used in different industrial applications for nearly a century. Due to the wide range of plate designs, The current investigation also presents the in-depth analysis of flow non-uniformity or maldistribution on the performance of plate heat exchangers Two symmetrical plates set with chevron angle, β = 60°/60° and 30°/30°, and one unsymmetrical plate set with chevron angle β = 60°/30° are used. In a single-pass U-type counterflow PHE, three different chevron plate arrangements are considered: two symmetric plate arrangements with β = 30 deg/30 deg and 60 deg/60 deg, and one mixed-plate arrangement Few experiments have been performed to investigate the hydraulic performance in a chevron brazed plate heat exchanger (BPHE) with the narrow channel at lower Reynolds number.
