Polymer density temperature dependence
WebMay 1, 2024 · The pressure-viscosity coefficient, α, is a measure of the pressure dependence of the viscosity of the liquid in elastohydrodynamic lubrication (EHL). There seems to be confusion around the understanding of the pressure-viscosity response in the inlet zone. In this paper the values of α were obtained from measurements of viscosity as … WebBy solving Equation 5 5 numerically, we would be able to obtain the density profile of a polymer melt at different temperatures. The data points generated numerically were fitted …
