本文研究了两个球体缓慢蒸发或凝结时的Stokes流。相变速度是规定的，并且在球体的表面上是均匀的。流函数和阻力的精确表达式。更简单的表达式适用于各种极限情况下（遥远的领域，一个源和一个领域，一个领域和一个平面）。当只有一个球体蒸发时，根据与另一个球体的距离，流动可能会表现出各种有趣的行为，如光滑边界分离，闭合再循环涡和无限开放涡。
The Stokes flow induced by the slow evaporation or condensation of two spheres is studied. The phase‐change velocity is prescribed and uniform over the surfaces of the spheres. Exact expressions are obtained for the streamfunction and the drag forces. Simpler expressions applicable to a variety of limit cases (distant spheres, a source and a sphere, and a sphere and a plane) are presented. When only one sphere is evaporating, depending on the distance from the other sphere, the flow may exhibit a variety of interesting behaviors such as smooth‐boundary separation, closed recirculating eddies, and infinite open eddies.
