Numerical study on the time-averaged movement characters of liquid-particle flows in rectangular pipes;

The application of three-dimensional k-ε-A_p model in the investigation of time-averaged movement characters of liquid-particle flows;

Firstly, utilizing the reverse screw, the characteristics of instantaneous motion of 3-RRRRR parallel mechanisms under its initial position and under the general condition were analyzed.

Through experimental research,this paper gets the characteristics of time average of fluid capacitance in differient operating mode of pump system,gives out the law of variation of characteristics of fluid capacitance with characteristics of pipe system and the inherent characteristics of fluid capacitance,analyzes the cause that make characteristics of fluid capacitance v.

The paper analyzes the influential factors for characteristics of time average of concentrated fluid capacitance in piping system.

In many situations the foodstuff machine and the packing machine is often needed to realize reciprocating continuously and especially in high automatic There are many such machines and each one has itself movement characteristic In terms of long time application and the writer analyses and discusses several; devices′s movement characteristic these devices can be controled easil

It summarizes the study and achievements on fluid mud definition, the formed mechanism and condition, the movement characteristics under the action of flow and waves and under the integrated actions of stormy waves and flow at seacoast and river mouth studied by scholars for a long time.
