The model is validated against experimental data from a tested mixed flow prototype. The results show that the model is consistent with the experiments with an error in the primary air temperature drop between 12% and 18%. Furthermore, a parametric analysis is performed to evaluate the effect of the size of the device. The temperature drop may double by increasing three times the height or the width of the device. In conclusion, this study reveals the importance of a proper calculation of the Nusselt Number, especially for the wet channel. Pages: 105 - 112 Paper:
