This study focuses on the prediction of hydrodynamic and hydroacoustic performance a cavitating marine propeller in open water condition using Reynolds-averaged Navier-Stokes (RANS) Detached Eddy Simulation (DES) solvers. The effectiveness methods is investigated for recently introduced benchmark that belongs to research vessel ‘The Princess Royal’. main emphasis examine capabilities RANS DES s...

Despite many advantages, hydrodynamic bearings tend to induce nonlinear vibrations on rotor systems at low external loads. The occurrence and also the amplitudes of these are very sensible operating conditions system such as gaseous cavitation, oil viscosity (strongly dependent temperature), bearing clearance (dependent metal temperature thermal expansion coefficients) or imbalance. This contri...

This short review provides the current state-of-the-art of in situ coupling of ultrasound to chemical deposition methods. A synergetic action of the ultrasound and light radiation or electrical fields may result in new powerful methodologies, and these include sonophotodeposition and sonoelectrodeposition processes. The effect of ultrasound is explained on the base of different physical mechani...

Abstract Cavitation inside a torque converter induces noise, vibration and even failure, these effects have been disregarded in previous design processes. However, modern applications require attention to this issue because of its high-speed high-capacity requirements. Therefore, study investigated the cavitation effect on using both numerical experimental methods with an emphasis influence cha...

A mathematical model is developed to investigate the combined effect of fluid cavitation and inertia on pressure buildup parallel textured surfaces. The analyzed using Rayleigh–Plesset model, with an averaged method. finite element method Newton-downhill are employed solve governing equations. numerical validated by comparing experimental results, discussed. research indicates that weakens dist...
