EFFECT OF CORRUGATION ANGLE ON PERFORMANCE EVALUATION OF PLATE TYPE HEAT EXCHANGER

MECHANICAL ENGINEERING

The design of plate heat exchanger is complicated due to large number of variables affecting the performance of the Plate heat exchanger and its geometry. Compact exchangers have many advantages over conventional heat exchangers. Compact heat exchangers are widely used for heat transfer applications in industries. Plate heat exchanger is one such type of compact heat exchanger which provides more area for heat transfer between two fluids. Plate heat exchangers are now a day widely used in many applications like heating and cooling application in food processing, chemical reaction processes, petroleum, pulp and paper, as well as in many water chilling application. The better heat exchanger is one that transfer's high heat rate at low pumping power with a minimum cost. In the current study I made a focus on researcher's efforts in research and developments for corrugated plate heat exchanger. Corrugation in plate increase mechanical strength of the plates and increase turbulence in the flow. It is very important to decide proper corrugation angle which give minimum number of plates at maximum effectiveness. Corrugation angle, corrugation depth these both parameters are very important to design the plate heat exchanger. The corrugations on the plates enhance turbulence at higher velocities, which improves the heat transfer.
