Hello
I try to solve a problem of natural convection from vertical flat at constant temperature using fluent 6.3.26 ,with working fluid is air ,the problem is a plate of 0.3m is maintained at a temperature of 40 c in a room of 30 c. 8. which isappropriatesolver? What is the properties of the air for this situation, in fluent the properties of the air is adjusted in the tutorial of modeling natural convection ?

first step is to calculate the Rayleigh Number, that will tell you if your flow is laminar or turbulent
Good luck
