The vehicles generator is one of the fundamental models of traffic simulation system and it provides traffic flow distribution over a period,including Poisson distribution,binomial distribution,negative binomial distribution,etc.

Design and numerical calculation of vane type swirl generator;

To investigate swirl and perfect evaluation criterion of engine/intake compatibility, a set of swirl generator was designed with adjustable blade turning angle, height and density.

To investigate swirl and perfect evaluation criterion of inlet/engine compatibility,a set of swirl generator was developed with adjustable blade turning angle,height and density.

Numerical simulation of heat transfer enhancement mechanism of small-scale vortex generator;

A source term model was applied to numerical simulation of a vane vortex generator,where the lift force created by a vane vortex generator was used as one part of the prototype of source term model,and a normal force was introduced as the other one.

The paper puts forward a new-type vortex generator enhancing heat exchange of solar air-drier and air-heater on the gas side and makes experiment and mechanism analyses have been presented.

The internal flow of a low-speed centrifugal compressor with and without vortex generator jet(VGJ)was simulated numerically by using CFD method.

The research development of vortex generator jet in flow control is reviewed from both sides of experiment measurements and numerical calculation.
