Theory of slightly perturbed three-dimensional flows in nozzles

Investigation of lateral forces and moments in the case of asymmetric gas flows in nozzles

“…It follows from the condition of no flow on the nozzle contour [9]. It follows from the condition of no flow on the nozzle contour [9].…”

“…To determine the lateral forces and moments, we shall in the present paper make wide use of the method of small perturbations developed in [9,13].…”

“…One of the equations is exact and follows from the condition of equilibrium of the end section of the nozzle [9].…”

“…In this connection, some authors have used the method of small perturbations [I, [9][10][11] to solve such problems.…”

Analytical study of supersonic isentropic flow in a channel of constant cross section and an adjacent laval nozzle. Comparison with numerical and experimental results

“….A 1, O, 6=0, successively using the invariants (11) Oscillatory flow in a channel of constant cross section was also obtained for the plane and axisymmetric cases in [10] within the framework of the small perturbation method . .A 1, O, 6=0, successively using the invariants (11) Oscillatory flow in a channel of constant cross section was also obtained for the plane and axisymmetric cases in [10] within the framework of the small perturbation method .…”
