Helical coil heat exchanger, Heat transfer coefficient, effectiveness, turbulence.
Conventional heat exchangers are large in size and heat transfer rate is also poor. Furthermore, in conventional heat exchanger dead zone is produce which lowers the heat transfer rate and to create turbulence in conventional heat exchanger some external means is required and the fluid in conventional heat exchanger is not in continuous motion with each other. Tube in tube helical coil heat exchanger provides a compact shape with its geometry offering more fluid contact and eliminating the dead zone, increasing the turbulence and hence the heat transfer rate. An effect of different tube shape and geometry with wire is wounded in the core to increase the turbulence in turn increases the heat transfer rate. This heat exchanger finds its application mostly in food industries and waste heat recovery.
