Abstract
The problem of linearized three-dimensional motions in a non-uniform flowfield is re-examined. Several modifications of the general analysis are effected. The influence of particulate matter is accounted for, to zeroth order and certain boundary processes treated in earlier one-dimensional computations are incorporated in an analysis applicable to any geometry. All processes occurring in combustion chambers are accommodated. As a specific example, the results are applied to a problem of linear stability in solid propellant rocket motors.
