Structure Parameter Optimization of Cross Flow Fan with Twisted Blade
摘要
Abstract
The three-dimensional internal flow field simulation of cross flow fans with 90° twisted blades in the electric fireplace system was researched and the influences of different structure parameters (volute throat gap, volute case gap, internal circumferential angle of the blade and external circumferential angle of the blade, blade numbers and the ratio of internal diameter to external diameter of the impeller) on the performance ( outlet volume flow rate) of the cross flow fan outlets were numerically researched. So we can get the optimal structural parameters with the optimal performance of the cross flow fans under the constant impeller rotating speed. By means of the self-built detection device of cross flow fan' s performance parameters, the air outlet average velocities of the 90° twisted blade cross flow fans were experimentally tested. The theoretical calculation results were consistent with the experimental test results. The above results provide an important reference for the optimal design of cross flow fans.关键词
