EFFECTS OF PARTICLE SHAPES ON THE KINETICS OF SOLID REACTIONS李建锡,高琼英,毛若卿,潘国耀摘 要:<正>In the paper,the effects of powder particleshapes on the kinetics of solid reaction (K. S. R) and errorscaused by the current methods based on spherical particlemodels have been studied. It has been found that particleshaeps have significant effects on kinetics......
hole. For console holes, particle deposition mainly takes place in the upstream area of the holes. Key words: gas–solid flow; particle deposition; film-cooled wall; converging slot film cooling hole... [10]. On the erosion issue, researchers have carried out more in-depth studies on the mechanism of sand erosion. The mass removed from a wall by an impact of a solid particle is determined mainly......
