Abstract
In a horizontal spray chamber occurs the phenomenon of mass transfer around every surface of water droplet. From Frossing's equation, the auther has developed the equation on the mass transfer rate of a single water droplet, the auther has developed the equation calculating the mass transfer coefficient of all water droplets in a spray chamber. (a) This is to be reduced to equation (19) if we neglect the perimeter effects of chamber wall and the calculated results are shown in Table 1. (b) Taking the perimeter effects into consideration, the mass transfer rate k_gaV is given as equation (19). The calculated results are shown in Fig. 11 and 12, involving the clear effects of wall and the aspect ratio with the section of spray chamber respectively in case of practical spray chambers as shown in Table 3 in dimension. For the spray chambers of any dimension, k_gaV can be also calculated from equation (24)-(27) with Ω value in Fig. 9.
