How to simulate without any flow conditions? FloEFD

Hi All,
I wanted to heat the water in a enclosed vessel. Say q=500 w/m2 on bottom surface of vessel. Please let me know how to solve this problem using FloEFD. Regards, Vigii |

Hi Vigii,
Ok, so you say it is an enclosed vessel. Is the vessel fully filled with water or just a little? If the vessel is fully filled with water, you can simply apply a surface source on the bottom surface of the vessel with the 500W/m^2 you mentioned. If you use an internal simulation, FloEFD will ask you for a flow condition as it expects to have some flow at all. If you don't want to define any, then you can chose external flow and simply define the outer walls of the vessel as adiabatic by setting the boundary condition wall to 0 heat transfer coefficient. With that there will be no heat transfer outside of the vessel similar to the default setting for internal flow. You will still have air or water (depending on your fluid settings) around the vessels geometry if it is not rectangular as the computational domain but there will be no exchange of heat. I hope this helps. Boris |
