Abstract Heat exchanger is an important device in all the thermal systems. The heat exchanger is widely used equipment in different industries such as process, petroleum refining, chemicals, pharmaceutical and paper etc. after studying different literature about heat exchanger and double pipe heat exchanger problem is identified as To perform simulation and experimental investigation of double pipe heat exchanger with inner and annuals twisted tape at different mass flow rate .
The system has followed different types of flow arrangement and geometric dimension with twisted tape to attain heat transferred in experimental result and compare with simulation result. The objective of these experiments is to Performance analysis of double pipe heat exchanger with inner and outer twisted tape at different mass flow inlet of hot. The experimental set up consists of double pipe heat exchanger experiment. The apparatus includes tube-within-a-tube heat exchangers and twisted tap with threaded thermocouple at each end, a water pump and electric motor. These methods used to find out the heat transfer rate from the surface and related temperature of fluid motions also used to found the effectiveness. The Annular method in which twisted tape is outside the inner tube has higher rate of heat transfer than other three methods. Also same result near found by simulation using ANSYS.
Keywords double pipe heat exchanger, inner twisted tape, outer twisted tape.
