N2 - A comprehensive model predicts combined impingement and through air drying time and the contribution in water removal from impingement and through flow. Experimental results verify the model. Prediction of drying time reduction for combined impingement and through air drying from that of pure impingement drying was made using the ratio of through flow mass flow rate to the total inlet air flow rate. The parameters considered included paper basis weight, drying air temperature, inlet air mass flow rate, paper initial moisture content, and two nozzle geometries. Through flow can significantly reduce the drying time from that of pure impingement drying. The reduction of drying time from that of impingement to that of pure through drying is highly nonlinear. The model can help in parameter selection for a CITAD dryer design. Application: The model results will help design an impingement dryer, through dryer, or combined impingement and through air dryer.
