Steady flow of a viscous incompressible fluid past two particles at moderate Reynolds numbers

A study is made of axisymmetric flow past two particles of spherical shape at Reynolds numbers 1 R 80. The flow patterns, pressure distributions, and values of the drag are investigated for different distances between the spheres. It is found that the drag depends nonmonotonically on the parameters that determine the flow.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 1, pp. 167–171, January–February, 1982.
