Simulation of Mixed Convection in a Channel with Cavity Heated From Different Sides Using Fluent

摘要

Computational Fluid Dynamic (CFD) is one of the methods used in industry and in education to solve problems related to fluid flow in closed channel. Through simulation, the type of fluid flow, streamlines and vor- ticity can be seen to determine the ability of the airway is produced through a rectangular shape to remove contaminants that are trapped in it. In addition, the project is also looking at the effects of conductive heat transfer that being supply at the sided wall to the water flow and it will be seen whether able to help the flow of air to remove pollutants altogether. Time is the element that is reviewed and any. Interest in the rate of contaminants being transfer was varied by the investigated ratio of neither 2:1, 4:1 nor 1:2 to the length and width in 2D simulation for best possible cavity design. The removal percentage shown that as the aspect ratio increase, the removal rate also increase with steady flow constant.
