Procedure of calculation of Average Nusselt number: Three ways: 1) in your code, sum all your Nusselt number values for one patch (not all patches) times de area of each element; sum all areas of elements/cells of the same patch; divide the nusselt values sum by the area sum. 2) in paraFoam, use filter … WebI am trying to calculate the Nusselt number in a rectangular enclosure in COMSOL, using the basic formula Nu=hL/k where h can be found from the heat flux, please, can anyone help me to do it right? Actually, I don't know how can I define this formula in derived value? which heat flux must be taken? thank you for your help. evacuation center hd

Web9 mrt. 2011 · Calculating Nu using gradients is not recommended in Comsol. Instead you can use the reacf (T) operator to calculate the heat flux and use it in the Nu calculations, which is the most accurate method.
