It can basically reflect the additional viscosity pressure drop due to flow path difference and additional inertial pressure drop due to high speed convergent flow.
该模型从本质上反映了因流线差异造成的粘性附加压降损失和高速紊流效应造成的惯性附加压降损失。

The flow rate, pressure drop, die swelling and apparent viscosity in dynamic and static extrusion can be measured by using this equipment.
利用该仪器可以测量聚合物在稳态和动态挤出过程中的流动速率、压力降、离模膨胀和表观粘度等。

A new droplet breakage criterion and a modified model of droplet breakage frequency which account for the effect of dispersed phase viscosity on drop deformation and breakage were presented.
