A study was conducted to reveal the curves of neutral stability for the stratified suspension flow in the plane channel within the framework of the modified model of interpenetrating continua. It was showed that unstable waves existed for Reynolds numbers lower than unity. The the model of interpenetrating continua with modifications was used for describing the dispersed flow, taking into account the volume fraction of inclusions through the corrections to the effective medium viscosity and to the interphase force. It presented the system of governing equations describing the suspension flow in dimensionless form assuming that the length and velocity scales were the half-width L and the suspension velocity Uo at the channel axis. The abscissa axis of the Cartesian system of coordinates was directed along the suspension flow in the channel and the ordinate axis was perpendicular to the channel walls.
