Numerical Simulation of Induced Alterations of Flow Patterns within Glass Melts using External Lorentz Forces
A common way to produce glass is to use melting tanks that work continually with several hundred tons per day.The process of efficiently melting,refining,and homogenizing the glass melt is strongly dependent on the flow patterns within the melting tank.In order to improve the quality of glass products and the efficiency of the melting process,it is necessary to control the flow patterns and to optimize the temperature distribution within the melting tank.Using Lorentz force to create additional flow components based on electric current density distributions and externally generated magnetic fields is an excellent method to obtain targeted and tailored flow influences.In order to evaluate this method,it is necessary to simulate the induced alterations of the melt flow.Such numerical simulations require the coupling of the electromagnetic and flow field calculations including the energy equation because the electrical conductivity of the molten glass is strongly dependent on the temperature.The idea is to include the calculation of the magnetic field completely into FLUENT using the so-called User Defined Scalars(UDS)and User Defined Functions(UDF).
