Numerical modeling of scrap heating by burners

For accurate prediction of flow and temperature field for the scrap heating by burners variable porosity, non-Darcian, turbulent flow with separate temperatures for gas and solids need to be considered. To handle these issues an in-house computer model was developed, considering non-uniform porosity inside the furnace, turbulence, dynamic behavior of porosity due to localized melting. The major challenges during numerical modeling were to use …
