Numerical Study On Using Of Nanoparticle In Economic Improvement Of Shell And Tube Heat Exchanger

Economic optimization of shell and tube heat exchanger (STHE) is presented in this paper. To increase the rate of heat transfer, copper oxide (CuO) nanoparticle is added into the tube side fluid and their optimum results are compared with the case of without nanoparticle additive. For this purpose, total annual cost is considered as objective function and nine design parameters including tube arrangement, tube diameter, tube pitch ratio, tube length, tube number, baffle spacing ratio, baffle cut ratio, flow allocation as well as particle volumetric concentration are selected. The optimum result show significant cost reduction (8.9%) in the case of nanoparticle additive compared with case of without nanoparticle additive. The lower tube inside diameter, lower tube number and lower baffle spacing ratio are chosen in the case of nanoparticle additive compared with the case of without nanoparticle additive.
