| Summary: | Numerical flow simulations are performed in lieu of actual experiments in biomanufacturing processes such
as injection molding and resin infusion to minimize costs of time and resources. However, such models are
usually developed through empirical studies and are limited in terms of their usability depending on the
specific conditions. As an alternative, a more general equation model based on an entropy-consistent
numerical scheme that includes the physical viscosity is developed herein. The scheme is applied to the Euler
system of equations to see how the physical viscosity term effect discontinuous flows and how it compares to
standard conventional models. A series of tests were conducted, in which the viscosity values were varied. It
was found that for high viscosity conditions, the entropy consistent scheme is comparable to the other
conventional models and therefore is a viable choice for further development |
