A study of chevron type plate design on pressure drop and friction factor of brazed plate heat exchanger

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract Brazed plate heat exchanger (BPHE) was analyzed using computational fluid dynamics (CFD) simulations by ANSYS Fluent to investigate the chevron‐patterned plates. The influence of geometric parameters, including corrugation pitch, depth, and angle was analyzed.
