Buoyancy induced flow and heat transfer inside a semicircular eccentric enclosure

This paper presents buoyancy induced flow and heat transfer performance inside a semicircular enclosure with isothermal upper and lower surface. The differential forms of governing equations are solved using Finite-Difference method. Simulation was carried out for range of eccentricity, ε = 0.2 to 0.6 at a fixed radius ratio Ro /Ri = 2.0. Grashof number was varied from 1.0 to107. Results of eccentric enclosure are compared with the concentric (ε =0.0) semicircular enclosure with same radius ratio. Eccentricity has little dominance on heat transfer rate. But significant effect of eccentricity is observed on flow field.
