Experimental and numerical investigation of an axisymmetric free jet

Abstract

The experimental and numerical investigations of an axisymmetric jet issuing from a nozzle are reported here. Experiments have been carried out using hot-wire anemometer and theoretical predictions made using the finite volume technique.The <i>k-ɛ </i>models, with modified constants to take care of free shear flows, have been used for the physical modelling. The present investigations are aimed at comparing the predicted results with reported experimental measurements. The present numerical method along with <i>k-ɛ </i>model has been found to predict the flow quite well. Therefore, the <i>k-ɛ </i>model can be used with confidence for the evaluation of flow characteristics of similar turbulent flows.
