Studies on the Properties of Turbulent Jets : 6th Report, Round Buoyant Jet

Abstract

The round turbulent buoyant jet issuing vertically into quiescent fluid is studied analytically. Formulae on maximum velocity, temperature, concentration and entrainment rate are derived. These formulae agree well with the available experimental data for whole region of jet and plume. Quantitative classification as to the flow regime of jet, transition and plume are given for the nondimensional distance from jet exit.
