| Associated to the scholarship: | 17/11428-2 - Numerical Methods for Non-Newtonian Free Surface Flows: effects of surface tension, BP.DR |
Abstract In this project, we propose to investigate some recent methodologies to treat high elasticity fluid flows. In particular, we are interested dealing with viscoelastic free surface flows considering the effects of surface tension, as for example, the die-swell extrusion and injection moulding problems. The constitutive equations used to model the rheological behavior of the fluids will be reformulated based on energy estimate analysis. Moreover, we suggest study and include a Lagrangian framework to solve the equations studying the characteristic in order to enhance the stability of the numerical schemes. Finally, these techniques will be extended for solving free surface problems using a finite difference discretization combined with MAC and front-tracking schemes. (AU) | |
