A 3-D time-dependent simulation of a laboratory scale inductively coupled thermal plasma torch system has been carried out to investigate unsteady turbulent flow patterns which may arise in the reaction chamber as a consequence of a sharp expansion of the gas at the torch outlet. A Large Eddy Simulation (LES) model has been used to predict the instantaneous flow field, without any time filtering as done in the RANS models (for example k- or RSM).

Abstract
A 3-D time-dependent simulation of a laboratory scale inductively coupled thermal plasma torch system has been carried out to investigate unsteady turbulent flow patterns which may arise in the reaction chamber as a consequence of a sharp expansion of the gas at the torch outlet. A Large Eddy Simulation (LES) model has been used to predict the instantaneous flow field, without any time filtering as done in the RANS models (for example k- or RSM).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
