Grid Free Method For Solving The Poisson Equation
- To simulate the influence of process parameters to the melt spinning process a fiber model is used and coupled with CFD calculations of the quench air flow. In the fiber model energy, momentum and mass balance are solved for the polymer mass flow. To calculate the quench air the Lattice Boltzmann method is used. Simulations and experiments for different process parameters and hole configurations are compared and show a good agreement. Keywords: Melt spinning, fiber model, Lattice Boltzmann, CFD.
