Abstract

This research is aimed to analyze the behavior of natural convection in the rectangular enclosure by varying wall temperature and using different types of fluid such as liquid metals, gasses, water and oil. In order to predict the behavior, Computational Fluid Dynamics (CFD) simulation tool ANSYS Fluent 14.0 is used to perform 2D and 3D simulation for various types of fluid (air, water, mercury and gasoline) with varying the temperature of one side of the wall in transient order. The boundary condition and operating condition for different type of fluid is defined too see the foreseeable effect of its changes to the simulation result. The result has shown various behavior of temperature contour and variation of velocity inside the enclosure. It also shows that the transient dispersion of temperature within rectangular enclosure is affected by the buoyancy forces acting upon the fluid, thermal expansion coefficient, density as well as the viscosity of the fluids. . Navier Stokes equation is further used to describe the temperature behavior of different fluids and different temperature changes schemes.
