| Abstract: | A study is made of the motion of a disperse medium with a low volume but high mass concentration of very inert particles. It is shown that in the framework of linearization of the equations the motion of such a medium will be irrotational if the oncoming flow is undisturbed at infinity. Simple expressions are proposed for estimating the influence of the particles on the drag of a body of arbitrary shape moving in the medium and also for the determination of the flow velocity by means of a Pitot-Prandtl tube.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 3, pp. 164–167, May–June, 1982. |
