原始语种摘要: This paper examines the effects of thermal buoyancy on momentum and heat transfer characteristics of symmetrically and asymmetrically confined cylinder submerged in incompressible Poiseuille liquid. The detailed flow and temperature fields are visualized in term of streamlines and isotherm contours. The numerical results have been presented and discussed for the range of conditions as 10 ≤ Re ≤ ≤ 40, Richardson number 0 ≤ Ri ≤ 4, and eccentricity factor 0 ≤ ε ≤ 0.7 at Prandtl number Pr = 1, and blockage ratio B = 20%. The representative streamlines and isotherm patterns are presented to interpret the flow and thermal transport visu¬alization. When the buoyancy is added, it is observed that the flow separation di¬minishes gradually and at some critical value of the thermal buoyancy...
