Abstract

The laminar Newtonian flow and heat transfer phenomena across a semi-circular cylinder have been investigated in the steady regime under aiding buoyancy. A through validation study has been carried out for Reynolds number (Re) =1 - 30 and Richardson number (Ri)=0 - 2 for a Prandtl number of unity. The numerical calculations are completed by using Ansys solver. The total drag coefficient shows a maximum percentage difference of about only 0.4% with literature. However, the corresponding maximum percentage difference in the values of average Nusselt numbers is found about 2.5%. Moreover, the maximum enhancement in the heat transfer is found approximately 28% with forced convection (Ri=0).

Item Type: Conference or Workshop Item (Paper)
Uncontrolled Keywords: Semi-circular cylinder, Reynolds number, Richardson number, Prandtl number, Nusselt number and Total drag coefficient.
