The problem of an axisymmetric translational motion of an incompressible microstretch fluid past an immiscible stationary microstretch droplet in the presence of a uniform magnetic field is investigated. The inertial terms in the equations of motion are neglected, therefore the microstretch scalar function is uncoupled from the stream function and microrotation component. Analytical solutions are obtained for the stream and microstretch scalar functions. The drag acting on the fluid droplet is evaluated. Numerical results for the drag force coefficient versus the relative viscosity, micropolarity parameter, and Hartmann number are tabulated and presented graphically. The results for the drag coefficient are compared with the available solutions in the literature for the limiting cases.

研究了在均匀磁场存在下，不可压缩的微拉伸流体经过不溶混的固定微拉伸液滴的轴对称平移运动的问题。运动方程中的惯性项被忽略，因此微拉伸标量函数与流函数和微旋转分量解耦。获得了关于流和微拉伸标量函数的解析解。评估作用在液滴上的阻力。将阻力系数与相对粘度，微极性参数和哈特曼数的数值结果制成表格并以图形方式显示。将阻力系数的结果与文献中极限情况下的可用解决方案进行比较。
