Abstract

Laminar flow and heat/mass transfer of a slot jet impinging in a rectangular cavity are studied numerically and experimentally. The discretization equations are formed by the finite-volume approach. Special attention is paid to the treatment of the outflow boundary condition. The influences of the jet-exit velocity distribution, the distance between the jet exit and the cavity bottom, and the Reynolds number on the local heat transfer distribution of the cavity bottom are investigated. In the experimental work, the local mass transfer coefficient distribution of the bottom surface is measured by the napthalene sublimation technique. The agreement between the numerical and experimental results is quite satisfactory.
