is also published as 3601968 Theory and calibration of a screen-type diffusion battery
A theoretical analysis of collection efficiency for screen-type diffusion batteries was made. The structure of stacks of screens can be approximated by a fan model of filter elements. The penetration equation was derived from the theory of diffusional deposition through a fan model filter. The theoretical equation is in good agreement with experimental data and, thus, useful in the calibration of the instrument.
