| Popis: |
This paper presents the effect of radius ratio on natural convection heat transfer and fluid flow inside an eccentric semicircular enclosure with isothermal upper and lower surface. Here laminar steady natural convection heat transfer inside the eccentric enclosure were observed for radius ratio R * =1.75, 2.0, 2.25, 2.5 keeping eccentricity (ε=0.4) constant. The differential forms of governing equations are solved by using Finite-Difference method. Simulation was carried out for ranges of Grashof number 10 1 to 10 7. Results are presented in the form of constant streamfunction, isothermal lines, local Nusselt number and average Nusselt number at different angular position. Radius ratio has significant effect on natural convection heat transfer as well as on flow field. |
