Hi all
My problem is a free convection flow and heat transfer in a box filled with water with a free surface (In the vicinity of air, like sea) and a cylinder at the middle of box that has 301 K. the water is 295 K. in CFX: 1- How can I active Buossinesq approximation? What is "Buoy.Ref. Temp" ? 2- What should I do about boundary condition of velocity and temperature on free surfacer? 3- what is the heat transfer coef and how much is it? 4- Thermal energy is correct? Thanks |

You should look into the documented tutorials, for example
Chapter 8: Buoyant Flow in a Partitioned Cavity The process of setting up natural convection model is described in detail. |
