Heat and mass transfer in spray drying - Dlouhy - 1960

Abstract. Studies of the evaporation and drying rates in an experimental concurrent spray dryer, 8 in. in diameter and 14 ft. high, are reported for various operating air temperatures. It was found that the total evaporation and drying time could be accurately predicted by employing a step-by-step method of calculation.

Numerical Calculation and Exergy Equations of Spray Heat

In the present study, the energy depreciation rule of spray heat exchanger, which is attached to a main fan diffuser, is analyzed based on the second law of thermodynamics. Firstly, the exergy equations of the exchanger are deduced. The equations are numerically calculated by the fourth-order Runge–Kutta method, and the exergy destruction is quantitatively effected by the …
