| 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. |
