線ー平行平板型EHDファンの速度分布に関する実験的および解析的検討

抄録

The purpose of this study is to reveal the characteristics of internal flow in wire-parallel plate electrode type electrohydrodynamic (ELD) fan and improve it to be more powerful fan. In order to understand the characteristics of the EHD fan more deeply, visualizations of the air flow in the flow channel and the exit area were conducted by using PIV and CFD analyses. In the experiment, air at atmospheric pressure and room temperature was used as a working fluid. Fan characteristics for the EHD fan, such as velocity profile and cross-sectional average velocity in the flow channel or at the exit area were shown as experimental results and considered in detail. In addition, the flow visualization, the instantaneous and time averaged velocity profiles by PIV analysis were shown while the comparison with experimental results described above, and differences of flow regime for different locations were discussed. Furthermore, two-dimensional steady state flow simulation by CFD analysis were also shown and discussed in consideration of experimental results.
