In this paper,the feasibility of the worm gear s modeling scheme by means of the variable section sweep and the toroidal bend feature has been discussed,and in accordance with the analysis of the principle to form a worm gear s tooth surface,a fairly reasonable modeling scheme is designed,with working out a worm gear s modeling in a relative simple way.
本文讨论了利用变截面扫描加环形折弯进行蜗轮建模的可能性,并根据对蜗轮齿面成型原理分析设计出一个较合理的方案,最终实现了以相对较简单的方式完成蜗轮建模的构想。
In a circular bend which is vertically up to horizontal, a numerical simulation for the two phase flow and concentration field of coal pulverized and air showed that the concentration near the back line of the outside in bend is higher than the concentration of the inside obviously.
对竖直上升转水平圆形弯管内煤粉空气两相流场和浓度场进行数值模拟表明 ,弯管外侧壁脊线附近煤粉浓度明显比内侧高 ,验证了弯管的浓淡分离原理 ,为进一步实施提高浓淡分离效果的各种改造措施提供了理论依据。
