Optimising the flow through a concertinaed filtration membrane

Abstract:

Membrane filtration is a vital industrial process, with applications including air purification and blood filtration. In this paper, we study the optimal design for a concertinaed filtration membrane composed of angled porous membranes and dead-ends. We examine how the filter performance depends on the angle, position, thickness, and permeance of the membrane, through a combination of numerical and asymptotic approaches, the latter in the limit of a slightly angled membrane. We find that, for...
