Abstract

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
