【Abstract】 By using the basic equations of the ideal flow field in the scroll of the centrifugal turbomachinery, the equations of speed gradient in the quasi—orthogonal direction for the comprcssiable and uncompressiable flow field are deduced. They are applied to the calculation of the flow fields in scrolls of centrifugal fans or centrifugal compressors. The results of the calculation are compared with those of the experiments and the useful informations are obtained.更多还原
