The calculation is based on the Efficiency-NTU-Method.
The number of transfer units NTU is calculated with the total heat transfer coeeficient htot, the surface area A and the minimum heat capacity flow consiting of the mass flow rate ṁ and the specific heat capacitiy cp.
NTU = (htot A) ⁄ (ṁ cp)min
Using the number of transfer units and the cross-flow portion of the whole transfer area the coeefficient for the heat transfer reduction is calculated.
