NUMERICAL SOLUTION OF NATURAL CONVECTION FLOW AROUND A HORIZONTAL ISOTHERMAL CIRCULAR CYLINDER USING FINITE VOLUME METHOD

摘要

Natural convection flow of air around a horizontal isothermal Cylinder is solved by finite volume method of laminar Navier-Stokes equations. In this study, the artificial compressibility of Chorin is used to solve the governing equation. The numerical results for local and average Nusselt numbers show a good agreement with literature studies. Present results are obtained for Pr=0.7 and 10 < Ra < 10~4.
