Entrainment characteristics of buoyant axisymmetric plumes in atmospheric inversions
Abstract
It is shown that the entrainment in a buoyant thermal plume from a power plant is controlled by the initial buoyancy and the atmospheric inversion rate. The spreading of the plume, corresponding to horizontal outflow from the plume, occurs after the plume has attained negative buoyancy. The effect of atmospheric inversion rate on the entrainment parameter is initially small but becomes dominant in the region of negative buoyancy.
