Title:Thin compression molding with Navier's slip conditions
Seminar:CCMA PDEs and Numerical Methods Seminar Series
Speaker:Ming Fang, Norfolk State University
Abstract:
Abstract: The compression process is one of the widely used process technologies in the rubber, elastomer, polymer industries and so on. In this study, we first derive systems of equations for a non-isothermal, non-Newtonian fluid in a thin compression moulding using Lubrication Approximation of Reynolds, Hele-Shaw assumption, and Navier's partial slip condition. Our study proves that the wall slip behavior can be predicted by the viscosity material function and thickness of the mold. Our numerical experiments reveal that the wall slip can result in the flow behavior that contrasts sharply with the well-known fountain flows in injection molding and Hele-Shaw literatures . We then prove the existence and regularity of weak solutions to the initial boundary value problems for a non-isothermal Newtonian case in a more general setting.
