Bubble-bubble interactions are of great importance for bubble dynamics. A mathematical model describing the dynamics a cluster in hydrodynamic cavitation is presented. The interaction strength (i.e. number density bubbles) introduced into Keller-Misis equation. Using this model, numerical investigations radial motion and internal energy) single have been made due to linear pressure gradient. Wi...

Venturi-type cavitation reactors still appear as the most promising candidates for industrial-scale production due to their cheapness and ease of construction, scaling, replicability. The effects temperature on hydrodynamic cavitating flows in a Venturi section are investigated find optimum reacting conditions enhancing treatment intensity. flow varied with 4 different rates wide range temperat...

We consider steady potential hydrodynamic-Poisson system with a dissipation term (viscosity) proportional to a small parameter in a two or three dimensional bounded domain. We show here that for any smooth solution of a boundary value problem which satisses that the speed, denoted by jr' j, has an upper coarse bound e K, uniform in the parameter , then a sharper, correct uniform bound is obtain...

In this study an attempt has been made to study the hydrodynamic performance of pumpjet propulsor. Numerical investigation based on the Reynolds Averaged NavierStokes (RANS) computational fluid dynamics (CFD) method using structured grid, SST kω turbulence model has been carried out. The grid independence inspection is applied to verify accuracy of numerical simulation. The numerical prediction...

Cavitation and cavitation erosion are complex hydrodynamic behaviors that significantly influence the stability reliability of pumping units in aerospace navigation power systems, hydraulic engineering, other fields. Studies on have primarily heavily focused collapse multiple bubbles; understanding movement bubbles is important for research. In this study, process near-wall double-cavitation wa...

Power ultrasonic reactors have gained a lot of interest in the food industry given the effects that can arise from sound induced cavitation. However, most of the new food processing developments have been based on empirical approaches. Thus, there is a need for mathematical models which help to understand, optimise and scale up ultrasonic reactors. In this work, a CFD model has been developed, ...
