Study on polymer flow profile in micro hot embossing;

In this paper the evolutionary process of fluid flow regimes of the retained oil displaced by bio-surfactants after water flooding was presented in laboratory test as follows: partial protuberance,growth in length,prolongation to oil silk;fracture of the oil silk,quick retraction to small oil particles;movement to the well bottom after their coalescence to large particles,oil wall.

Plastic flow pattern and test analysis in friction stir welding;

Mechanism of flow pattern affected by corrugation geometric parameters in the chevron-type plate heat exchanger;

Based on experiments,this article sets out to prove that the difference in Reynolds value,on which fluids'flow patterns are decided,results from variations in experimental devices and conditions.
