Numerical and Experimental Models of the Thermally Stratified Boundary Layer

Numerical and Experimental Models of the Thermally Stratified Boundary Layer

The article describes a change of selected turbulent variables in the surroundings of a flow around thermally loaded object. The problem is solved numerically in the software Ansys Fluent using a Transition SST model that is able to take into account the difference between high and low turbulence at...
