HEAT, MASS, AND MOMENTUM TRANSFER BETWEEN A HIGH VELOCITY LIQUID JET AND A CONCENTRIC GAS STREAM IN AN AXISYMMETRIC CHANNEL
Abstract
The study began with an effort to determine whether the liquid stream entering the mixing section of an ejector-like device remained intact in a jet or atomized. The conclusions were that for the range of variables of interest the probability was that there was no significant jet breakup. Possible entrainment of liquid by the concentric gas stream has been neglected at this time. Having established an analytical model based on the assumption that the liquid stream remains intact, the basic equations were numerically solved for a variety of conditions. Using the axial distance required to condense the vapor from the concentric gas steam onto the liquid jet as a measure of performance, (the shorter the better), it was found that: (1) A constant pressure converging mixing section is more effective than a constant area mixing section; (2) Increasing the number of liquid jets (constant total jet flow area) shortened the mixing section. (3) Increasing the Mach number of the gas stream at the mixing section inlet shortened the mixing section. (4) The amount of noncondensable present in the gas stream (from 20 to 50 percent by weight) did not significantly affect the distance required for condensation but did affect the shape of the mixing section.
