CFD ANALYSIS OF AN AUTOMOBILE RADIATOR WITH AND WITHOUT LOUVERED FINS USING NANO FLUIDS

Abstract

Radiators are heat exchangers used to transfer thermal energy from one medium to another for the purpose
of cooling and heating. The majority of radiators are constructed to function in automobiles, buildings, and electronics.
The radiator is always a source of heat to its environment, although this may be for either the purpose of heating this
environment, or for cooling the fluid or coolant supplied to it, as for engine cooling. Despite the name, most radiators
transfer the bulk of their heat via convection instead of thermal radiation. Spacecraft radiators necessarily must use
radiation only to reject heat.
A fin is a thin component or appendage attached to a larger body or structure. Fins typically function as foils
that produce lift or thrust, or provide the ability to steer or stabilize motion while traveling in water, air, or other fluid
media. Fins are also used to increase surface areas for heat transfer purposes, or simply as ornamentation.
In this project, we intend to develop a model of fin with louvered section. The two variations of fins are taken such that
initial is a rectangular fin and the latter is a trapezoidal form. The tubular of 5 sections are developed for the fins. The
models are modeled in Catia V5 R20 and analyzed in fluid dynamics computational analysis is done in Ansys 15.0 with
fluent interface.
