CONVECTIVE PLUMES IN POROUS MEDIA: THE EFFECT OF ASYMMETRICALLY PLACED BOUNDARIES

摘要

A boundary layer analysis is performed for the free convective plume in- duced by a uniform line source which is placed at the intersection of two semi-infinite planes. Particular emphasis is placed on how the presence of the planes, which are not placed symmetrically with respect to the vertical, affects the direction of the plume. To this end, a two-term boundary layer expansion together and a one-terms approximation of the flow in the outer regions either side of the plume are performed using the method of matched asymptotic expansions.
