Thermal And Cfd Analysis For Finding Heat Transfer Through An Angular Bend Tube For Various Nano Fluids

Abstract

Heat transfer by convection is very important for many industrial heating and cooling applications. The heat convection can passively be enhanced by changing flow geometry, boundary conditions or by enhancing fluid thermos physical properties. A colloidal mixture of Nano-sized particles in a base fluid, called Nano fluids, tremendously enhances the heat transfer characteristics of the original fluid, and is ideally suited for practical applications due to its marvelous characteristics.

            In this thesis, different Nano fluids will be analyzed for their thermal behavior passing through an annular bend tube with turbulence flow. The Nano fluids considered in this thesis are Nano fluids made from base fluids ethylene and tri-chloro ethylene glycols, copper Nano fluid and aluminum Nano fluid. Thermal and CFD analysis is performed to determine the thermal behavior using finite element analysis software Annoys. 3D modeling is done in Solid works. Thermal analysis is also done on the tube in tube heat exchanger for water and better fluid of above mentioned Nano fluids.
