摘要(Abstract)：

采用包括流场计算、颗粒轨迹追踪和磨损值计算的数值模拟方法,研究了气固两相流对不同入口结构旋风分离器环形空间壁面磨损情况,计算得出的气相时均速度以及环形空间磨损区域与实验结果基本吻合。计算结果表明,不同入口结构分离器环形空间壁面都是以"局部磨损"为主,但磨损区域略有不同。在圆周方向上,蜗壳式入口结构壁面磨损主要发生在60°~200°,其中90°~180°磨损最为严重;单入口直切式结构磨损范围较广,主要集中在60°~210°;双入口直切式结构壁面磨损在环行空间分成两个区域,分别集中在60°~120°和240°~300°,磨损相对均匀;环形空间壁面磨损率沿周向的变化曲线完全不同,最大磨损率的周向位置也各不相同,蜗壳式结构最大磨损率相对较小。通过研究找到了一种有效的计算分离器壁面磨损的方法;改变分离器入口结构,可以改善环形空间壁面磨损情况,为分离器环形空间的防磨提供依据。
