The axisymmetric jet in a coflow
Abstract
The axisymmetric jet in a coflow has been modeled using the excess momentum equation, the continuity equation and an entrainment function to determine the approximate variation of the mean jet properties. The entrainment into the jet changes as the jet changes from a strong jet to a weak jet. The entrainment function allows for the additional entrainment occurring in the weak jet indicated by the more convoluted jet boundary. In the limits the model agrees with dimensional analysis.
