I completely overlooked at it. I was looking for a different name for it. My fault. No need to explain typical convection formula. According to the example values which I presume they are all in SI units. For 200 kph convection factor would be 8.4+0.6•200/3.6 = 42 W/m2K. This value is very low for high speed. The ground conductance value of 1000+0.03•P reported seems low for what I have read. Considering a load of 3000N spread in a 0.3•0.1 m2 patch would yield 100kPa. Overall conductance would be 1000 + 3000 = 4000 W/m2K. Reported figures in other papers suggest values way over 10000 W/m2K. I haven't still checked hysteresis values but I will. I am nit an expert in hysteresis so I will have to do some research. From my point of view the accuracy of main heating and cooling components has not been validated. They have fine tuned the numbers considering the average obtained final temperature but not in the theorerical correct way a simulation is validated. This yields to excessive temperature in front wheels in my opinion and too cool rear wheels. As an example of this. Recommended tire pressures for Radicals are basically impossible to achieve unless overinflating them and getting an uneven tire temperature distribution over the tread.
