Thermal plasma model for the existing thermal torch

developing a thermal plasma model for the existing thermal torch of ScanArc to support the experiments of WP3 A 3D fluid dynamics model will be developed within COMSOL based on the NavierStokes equations using the experimental plasma power and reactor dimensions as input This will provide information on the gas flow profiles plasma temperature and densities of the most important plasma species including neutral molecules radicals ions and electrons From the gas composition NOx concentration at the outlet the NOx yield will be predicted Based on the plasma power and gas flow rate which both determine the specific energy input in the plasma the energy consumption and energy efficiency of the process will be predicted The model will be finetuned by comparison with experimental data for the existing ScanArc and after validation the model will be used to scan a wide range of conditions flow rate plasma power geometrical variations for further optimisation of the NOx yield and energy consumption
