Notes:
Mass transfer coefficients have been measured for air flowing through a bed of naphthalene pellets. Results were obtained for ⅜-in. spheres and for ½, ⅜, and ¼-in. cylinders in a bed 4 in. in diameter and packed to heights varying from 5 to 10 in. Radial concentration profiles were obtained for some conditions, from which the radial variation of the mass transfer coefficient was determined. The point-values of kg follow an equation of the form kg = a Gb. From mixed outlet concentrations, values of kgav and jd, corrected for the effect of axial diffusion, have been obtained for all the pellet sizes as functions of mass velocity and Reynolds number, respectively.
