Numerical Simulation of Viscous and Viscoelastic Fluids Flow
Keslerová R., Kozel K.
Abstract:
This paper shows the results of the numerical modeling of viscous and viscoelastic fluids flow in the branching channel with T-junction. The mathematical models are Newtonian and Oldroyd-B model. Numerical tests are performed on three dimensional geometry, a branched channel with one entrance and two exit parts. Numerical solution of the described models is based on central finite volume method using explicit RungeKutta time integration.
Keywords:
Newtonian and Oldroyd-B fluids, generalized system of Navier-Stokes equations, finite volume method
