Simulation of Heat Transfer Phenomenon in Furnace Using Fluent-Gambit

Abstract

In this project work the simulation of heat transfer and the temperature curve in the furnace is computed out using gambit and fluent software. Comparison of temperature profiles of the material in the furnace using constant temperature heat source and linearly varying temperature of the heat source for unsteady state is done. Also the time for temperature to become steady is compared. The material used in the furnace is aluminum and conduction is the mode of heat transfer, the side walls are adiabatic and maintained at ambient temperature.
Also the density variation and solidification-melti

ng curve of material filled inside are compared
for both conditions. The geometry used is very simple, similar to muffle furnace. The problem
will be solved by using the software package FLUENT – GAMBIT. FLUENT is a computational fluid dynamics (CFD) software package to simulate fluid problems. It
uses the finite-volume method to solve the governing equations for a fluid. It provides the capability to use different physical models such as incompressible or compressible, in viscid or viscous, laminar or turbulent, etc. Geometry and grid generation is done using GAMBIT which is the preprocessor bundled with FLUENT.
