Thermal and Cfd Analysis For Finding Heat Transfer Through an Annular Bend Tube For Various Nano Fluids

Abstract

 

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 materials will be analyzed for their thermal behavior of an annular bend tube with turbulence flow. The materials considered in this thesis are ethylene glycol, copper and aluminum. Thermal and CFD analysis is performed to determine the thermal behavior using finite element analysis software Ansys. 3D modeling is done in PRO-E. CFD analysis is also done on the tube in tube heat exchanger for water for the above obtained best material materials.
