Fourth Order Accurate Free Convective Heat Transfer Solutions from a Circular Cylinder
نویسنده
چکیده
Laminar natural-convective heat transfer from a horizontal cylinder is studied by solving the Navier-Stokes and energy equations using higher order compact scheme in cylindrical polar coordinates. Results are obtained for Rayleigh numbers of 1, 10, 100 and 1000 for a Prandtl number of 0.7. The local Nusselt number and mean Nusselt number are calculated and compared with available experimental and theoretical results. Streamlines, vorticity lines and isotherms are plotted. Keywords—Higher order compact scheme, Navier-Stokes equations, Energy equation, Natural convection, Boussinesq's approximation and Mean Nusselt number.

On the natural convective heat transfer from a cold horizontal cylinder over an adiabatic surface
A steady two-dimensional laminar free convection heat transfer from a cold horizontal isothermal cylinder located above an adiabatic floor is studied both experimentally and numerically. In the experimental measurements the effects of cylinder distance from horizontal floor to its diameter (L/D) on heat transfer coefficient is studied for Rayleigh numbers of 3×105 and 6×105. Computations are ma...

A numerical investigation has been carried out for mixed convection flow in a rectangularventilated cavity with a heat conducting solid circular cylinder at the center. Forced convection flowconditions were imposed by providing an inlet at the bottom of the left wall and an outlet vent at the topto the other sidewall. In this paper, the effect of cavity aspect ratio as well as the mixed convect...
متن کاملStudy of heat-transfer on the surface of a circular cylinder in flow using an immersed-boundary method
An immersed-boundary method, previously developed for flow-field simulation, is extended to study heat-transfer problems of flow over a circular cylinder. The Dirichlet-type isothermal temperature boundary conditions and the Neumann-type iso-heat-flux boundary conditions are both implemented. To verify the accuracy of the simulation method, L2-norm are computed to test the order of accuracy of ...
