Review on Heat Transfer Characteristics for Corrugated tube in a Double pipe Heat Exchanger

The corrugated plate heat exchangers are widely used in food industry especially for pasteurization operations. The Double pipe heat exchanger is one of the Different types of heat exchangers because one fluid flows inside a pipe and the other fluid flows between that pipe and another pipe that surrounds the first in a parallel flow, both the hot and cold fluids enter the Heat exchanger at same end and move in same direction. In a counter flow, both the hot and cold fluids enter the Heat exchanger at opposite end and move in counter direction. The present study will be taken up to carry out review work for the calculation of heat transfer rate in Double-Pipe Heat Exchanger made of corrugated tube .It is observed that In experimental set up hot water and cold water will be used working fluids. The inlet Hot water will be around 70 °C and cold water temperature will be varied from between 20 to 38 °C. It has been planned to find effects of the inlet condition of both working fluid flowing through the heat exchanger for the heat transfer characteristics.
