Abstract. The changes in vortical and turbulent structure in the near field (X/D < 3.0) of jet mixing flow caused by a lobed nozzle were investigated experimentally in the present study. The techniques of planar laser induced fluorescence and particle image velocimetry were used to accomplish flow visualization and velocity field measurements. The experimental results showed that, compared with...

The vortical and turbulent structure changes in the near field (X/D<3.0) of the jet mixing flow caused by a lobed nozzle had been investigated experimentally in the present study. The techniques of planar Laser Induced Fluoresce (LIF) and Particle Image Velocimetry (PIV) were used to accomplish the flow visualization and velocity field measurements. The experimental results showed that, compare...

The bipolar plate is the fundamental structural element of hydrogen fuel cell, and its flow field design has a significant impact on performance cell. cell employed as an important energy supply source for vehicle power. classification operation cells, well benefits drawbacks conventional fields, are discussed in this paper contrasted with state research recent years. Comprehensive analysis don...
