Study on the pressure drop in the plate heat exchanger channel

In this paper presented pressure drop characteristics in one channel of plate heat exchanger by experimental method. Plate Heat Exchanger (PHE) applied in vacuum evaporator for product fresh water. PHE have become popular in chemical, power, food and refrigeration industries due to the efficient heat transfer performance, extremely compact design and flexibility of extend or modify to suit changed duty. The heat transfer part contains corrugated plates with 60 degree of chevron angle. The experiments carried out pressure profile according to mass flow rate at 15 measure points for investigate flow characteristics of PHE channel flow which highly turbulent even with low Reynolds number. In addition, numerical simulation was compared with experimental results and present more visible distribution of flow behavior in the test section.
