Abstract

In order to define the edge of a plume subject to off-source heating, referred to as a transient diabatic plume (TDP), it is necessary to define a boundary of such a plume. The vorticity magnitude (|ω|), appropriately scaled by suitable local length and velocity scales, has been used to determine the boundary turbulent/non-turbulent interface (TNTI) of the TDP. This enables us to use this value of (|ω |), to compute the true turbulent mass flux (MF) which is a measure of fluid entrained into the TDP.
