Abstract
This experimental study explores the effect of using compound technique (passive techniques (packing the shell side with small cylindrical aluminium pieces) and active techniques (air injection or bubble generation) were securitized. It is conducted for both configurations (parallel and counter) flow with applying both techniques (compound) at the same conditions in a double pipe heat exchanger. The main objective of this study is to indicate the effect of employing the two techniques simultaneously and compare the outcomes without and with the passive (packing) method under the same conditions. The heat transfer of heat exchanger in terms of cost and size has been For this purpose the test rig is prepared by designing and making a suitable heat exchanger equipped with flow meters and thermocouples for measuring flow rates and temperatures (Tin and Tout) of both fluids (hot and cold) . The hot fluid is heated in a small tank by electrical heater with temperature controller from (TEquipment). The results show that the performance parameters of the heat exchanger enhanced about (15%) for case of applying the both techniques together and (25)% for case of using active method only.
