Swapnil A. Dharaskar, Prashant R. Tayade

Abstract


Improvement in heat transfer coefficient in heat exchanger plays very important energy saving role in the industries. In this study the effect of ionic liquid on HT coefficient was studied using a lab scale shell and tube heat exchanger (length-39 cm, shell diameter 9 cm, Tube diameter 0.62 cm). Also the effect of cold and hot flow rate on heat transfer coefficient, Effect of mass concentration of ionic liquid was studied. This work deals with the experimental investigation of thermal conductivity and specific heat capacity of ionanofluids as a function of a temperature and concentration of (1-Butyl-3-methylimidazolium chloride) (BmimCL). Also, results using (BmimCL) as coolants in heat exchanger are also used to access their feasibility and performance in heat transfer devices. Overall good results were obtained with experimental work results on thermal conductivity and heat capacity of (BmimCL) as well as the estimation of heat transfer areas for ionanofluids and ionic liquids in a model shell and tube heat exchanger reveal that ionanofluids possess superior thermal conductivity and heat capacity and require considerably less heat transfer areas as compared to those of their base ionic liquids. This novel class of fluids shows great potential for advanced heat transfer applications the enhancement heat transfer of the heat transfer devices can be done by changing the fluid transport.
