Performance investigation on plate heat exchanger using nanofluid as working fluid / Ler Cherk Yong

Plate heat exchanger (PHE) is a kind of heat transfer equipment that made up of a pack of thin corrugated metal plate that promote heat transfer between two fluids. Water as the most common heat transfer medium has low thermal conductivity that result in lower overall heat transfer coefficient. With...
