Hi Rob, thank you for your answer.
My current model does not take solar radiation (eg through a window) into account. I will model solar radiation in a later step.
The local velocity of air is used to calculate the PMV, but as far as I know, for the Draught rate I need a measure for local turbulence. I am slightly confused with the terminology here, since in german there is something called "Turbulenzgrad", which translates approximately to "turbulence intensity". Its defined locally as follows:
TU = 100 * standart deviation of velocity / mean velocity [%] This is how i measure turbulence in the laboratory. The measurements are used to "calibrate" my CFD-Model.
I found following equation in Fluent theory guide:
Tu = 100/u *(k*2/3)^0.5 ,unit is also % i guess.
Do these two expressions describe the same?
I do have access to the customer portal, I couldnt find something on this in Solutions. Can I ask for a hint where exactely to look for such a udf?
