二维透平叶栅流道中总压分布的彩色图象显示研究

AN INVESTIGATION ON THE COLOUR IMAGE VISUALIZATION OF HE TOTAL PRESSURE DISTRIBUTIONS WITHIN THE PASSAGE OF A PLANAR TURBINE CASCADE

本文采用微型计算机的彩色显示功能,对大尺度、小展弦比、大转折角二维透平转子叶栅流道内横截面上的总压分布进行了彩色显示研究。文中给出的测量截面上总压分布的彩色图象照片,可直观地看出通道涡在不同横截面上的尺度、位置和粘性涡核强度的变化。

Adopting the function of colorer image display with a mi-crocomputer,this paper have carried a study of colour image visualiza-tion on the total pressure distributions in traversed planes within thepassage of a planar turbine rotor cascade with large scale,low aspectratio and highly turning angle.From the colour photographs of the to-tal pressure distributions measured in the traversed planes given in pre-sent paper,some variations of the passage vortex in its scale,positionand the strength of its viscous core can be observed intuitively.
