Abstract:
A plane problem of unsteady jet outflow of an inviscid incompressible imponderable fluid through an orifice in a wall is considered in the presence of a variable-strength point source in a symmetry plane of the flow. The velocities of perturbed flow induced by the change in the source flow rate are assumed to be small compared to stationary flow velocities. The Gurevich–Haskind method is used to solve the problem. A boundary value problem for the complex potential of the perturbed flow is formulated and solved. The pressure distribution on solid walls is determined for the harmonic source strength variation with time. The evolution of the shape of the jet's free boundary is studied.
Key words:inviscid incompressible fluid, jet flow, point source, unsteadiness.
