In the present article, the special effects of fluid inertia forces and magnetic field in circular squeeze film bearings greased with a time‐independent thixotropic non‐Newtonian fluid have been brought to the limelight. The pressure delivery and load carrying capacity representing the recitals of bearing have been calculated with the values of yield number, thixotropic parameter, power‐law index, Reynolds number, and Hartmann number. The squeeze film pressure and load carrying capacity are increased with the rise of yield number, power‐law index, Reynolds number, and Hartmann number whereas a reverse trend is shown with the increase of thixotropic parameter or a scalar structural parameter of materials. Based on the results obtained from the present study, the influence of thixotropic fluid enhances the pressure and load carrying capacity as compared to pseudo‐plastic, Newtonian, and dilatant fluids as lubricants.

磁力和非牛顿特性对挤压薄膜轴承的影响

在本文中,使用时间独立的触变非牛顿流体润滑的圆形挤压膜轴承中的流体惯性力和磁场的特殊影响已引起人们的关注。用屈服值,触变参数,幂律指数,雷诺数和哈特曼数的值计算了代表轴承独奏的压力传递和承载能力。挤压膜的压力和承载能力随着屈服数,幂律指数,雷诺数和哈特曼数的增加而增加,而随着触变参数或材料标量结构参数的增加呈现出相反的趋势。根据本研究的结果,
