natural convection simulation in an infinite medium

me_geo · June 15, 2013, 07:26

Hi, I am trying to simulate a natural convection problem in ansys fluent Problem description is as follows:

An isothermal circular cylinder at temp T1 kept in open air extending to infinity.i would like to simulate the natural convection happening outside cylinder ie my domain is the air outside the cylinder I would like to know what Boundary condition i can give for air which extends to infinity and what should be the extend of my domain?

it would be of great help if someone can help me with this simulation.

Thanks in advance
