On the elasticity of polymer fluids
关键字：fluid elasticity polymer fluids die swell inlet pressure drop References
It was showed in literatures that polymer fluids (as melts or solutions) which have similar viscosity but different elasticity, their theological and processing behaviors were widely divergent.The measure method and norm for fluid elasticity are not a circumstance to fluid viscosity. The physical quantities to describe of fluid elasticity in literatures were various [1-2] There are distinguishe...
