Abstract
Heat exchangers have always been an important part to the lifecycle and operation of many systems. A heat exchanger is a device built for efficient heat transfer from one medium to another medium. Shell and tube heat exchanger is an indirect contact type heat exchange as it consists of a series of tubes, through which one of the fluids runs. Shell and tube heat exchange which is the majority type of liquid-to-liquid heat exchanger with baffle for induced turbulence and higher heat transfer coefficient. Shell and Tube heat exchangers are having special importance in boilers, oil coolers, condensers, pre- heaters, power plant, chemical plants, petrochemical plants and automotive applications and refrigeration and air conditioning industry.
This paper discusses the design and analysis of shell and tube heat exchangers by considering different fluids, Nano fluid, Hybrid Nano fluids (fluids has water(h2O), Nano fluids has aluminium-oxide and copper (Al2O3 and cu) and Hybrid Nano fluids has aluminium oxide -copper (Al2O3-cu/h2O)) which is mixed as distilled water (h2O) and their ability to transfer heat from the surface. Temperature distribution, heat flux and thermal gradient in heat transfer analysis, also when we do structural analysis for heat exchanger by using ANSYS Fluent CFD analysis software.
