Plate Heat Exchangers (PHEs) are increasingly used in process industries due to their compactness, as well as higher reliability and operability compared to conventional shell-and-tube heat exchangers. Heat transfer in PHE takes place in channels of complex geometry formed by corrugated plates placed abutting. The flow in such channels can be very complicated due to breakup and reattachment of the boundary layer, secondary flows and the small hydraulic diameter of the flow passages. The aim of this work is to compare a well-established and validated CFD code both with experimental results obtained from industrial applications of PHE and with existing correlations. The results show that CFD simulation can predict heat transfer rate and fluid flow behaviour in a range of Re numbers (3,200 to 9,450), with discrepancies up to 1% and 6% in terms of outlet temperature and pressure drop respectively.
