Hello,
I am working on natural convection on a vertical heated plate. I set the plate temperature high (~700 K), so it seems that the flow over the plate is turbulent flow. These are my questions: 1. Most of properties for Air 25 C have constant value. Is there the built-in properties of the air depending on temperature? 2. What value of y+ should I use in meshing procedure for simulating the viscous sublayer? Please give me suggestions. Thank you in advance! |

1) No. You will have to define it yourself.
2) You need to do a sensitivity study to establish this. Are you sure you need to model the sublayer? You might be turbulent enough that wall functions are OK and then meshing is much easier. |
