Abstract
A numerical study of mixed convection and flow inside an eccentric horizontal annulus is presented. The inner and outer cylinders rotate to generate the forced convection effect. The numerical work was carried out using ANSYS FLUENT 16. The numerical study is conducted for laminar flow mixed convection. Different eccentricity angle were studied to get the best position of eccentricity at which the best heat transfer occurs. The effect of eccentricity angle on the average Nusselt number at constant radius ratio of 2 and constant eccentricity of 0.5 is conducted. All results were performed with constant heat flux=400 W/m2 at the inner cylinder and constant inlet velocity. isotherms was investigated.
