Velocity fluctuations and plasma-like screening in sedimenting suspension
In this short talk I will present the problem of diverging expressions for velocity fluctuations in a stationary state of uniform sedimenting suspension. Those divergencies, as suggested by Koch and Shaqfeh, can be eliminated by plasma like screening conditions for correlation functions. Unfortunately BBGKY hierarchy for that system derived by Cichocki and Sadlej can not have solutions which obey those conditions.
