Abstract
Volumetrically heated jets mimic fluid flow in cloudy plumes, and the entrainment rate coefficient in such jets can vary significantly along the axial direction. In this work, we formulate an energy consistent Gaussian integral model for volumetrically heated jets, in which the entrainment rate coefficient is dynamically evolved along the axis. The widths for radial profiles of velocity, tracer concentration, and temperature are allowed to evolve separately. The results from the model agree reasonably well with corresponding integral statistics obtained from Large Eddy Simulations.
