For fluid of air,interaction between vortices induced by vortex generators in the flat-tube-fin heat exchanger and heat transfer performance of radiator have been investigated by a method of numerical simulation in the Reynolds number range of 500~2 100.

In this paper,we have studied the interactions and the evolution of two vortices with different rotate directions genenratated by two vortex generators both by the flow visualization method and the numerical simulation method.

A numerical study of interactions of vortices generated by VGs and the effects of such interactions on heat transfer enhancement of flat tube bank fin are carried out.

At the same time, distributing characterization of flow field, including forced vortex, free vortex, compound vortex and spiral vortex, inside hydrocyclones was analyzed and calculated.

Aiming at the non-uniform plasma application in aircraft stealth,a piecewise linear current density recursive convolution finite-different time-domain(PLJERC-FDTD) algorithm is applied to the study on the scattering for the plasma vortex and plasma vortex cluster.

When the endwall is stationary,vortexes appear near left-below and right-below of the endwall,and then vortexes center moves toward up and middle,the vo.
