The optimal control problem of profiling the hydro-cannon nozzle to obtain the maximum outlet speed

AbstractThe hydro-cannon is, an interesting and a promising installation for producing high-speed pulsed liquid jets (1–3). It uses the inertial principle of fluid acceleration. The key feature of the hydro-cannon is that the dynamic pressure of the jet can be many times higher than the static one inside the installation. Hence, the form of the hydro-cannon nozzle is essential for the acceleration process of the water. The paper deals with calculation of the nozzle profile to obtain the maximum outlet speed.
