review text: The stability investigation is based on a concrete theory of the properties of finely disperse suspensions with randomly pulsating particles. Normal and also quasiviscous stresses develop in the dispersed phase as a result of the transport of pulsation momentum by the pulsations themselves and their effect on averaged momentum transfer in the shear flow. The theory makes it possible to find the conditions of neutral stability and the properties of the waves of maximum growth and, moreover, to give a natural explanation of the stabilizing role of the Brownian motion of the particles, important in connection with the transition from suspensions to colloids, and of the appearance of the well-known scale factor with increase in the linear scale of the flow.
