Abstract

One row of heated elliptical cylinder with aspect ratio 0.6 and 0.8 are studied to know the forced heat transfer performance. The transversal distance between the cylinders are changed and the heat transfer is observed. Numerical observation of the study is done by using finite volume method to solve the momentum equations in two dimension domains. The pressure term instead of velocity is obtained by measurement in a subsonic wind tunnel and then it is injected into the momentum equation. The results of the hydrodynamic calculation are then injected into the energy equation which is solved by the over relaxation iteration method. The results of numerical calculation show that the drag coefficient due to flow friction changes with the distance between two elliptic cylinders. At certain distance, the cylinders behave as single cylinder and no influence each other. The Heat transfer performance for small distance between the cylinders has lower values compared to larger distance. It increases with the increase of distances and at a certain distance, there is no more increases. It means that the heat transfer tends to a constant value. Heat transfer ability is depending on the aspect ratio of elliptic cylinder.
