摘　　要：以静压滑环的简化模型旋转对称密封缝隙为研究对象，建立了在变粘度条件下这种缝隙的数学模型，推导了其有限元模型，并对其进行了求解，得出了流体在这种缝隙中的速度场、压力场和温度场的分布规律．Taking as the object of research the rotational symmetrical seal clearancewhich is a simplified model of hydrostatic slide ring, this paper establishes the mathematical model of the seal clearance, and derives and solves the finite element modelFinally, the distribution laws of the velocity, pressure and temperature fields in theclearance are obtained.

关 键 词：密封缝隙 变粘度流体 有限元 静压滑环 流场
