چکیده

This article deals with the numerical simulation of unsteady cavitating flow around hydrofoils, supported by experimental research realized in a cavitation tunnel situated Centre Hydraulic Research. Two straight NACA hydrofoils (NACA0020 and NACA2412) were employed. The comprehensive CFD analysis was based on scale-resolving simulations (hereinafter SRS) aim capturing correctly interactions between structures re-entrant as well compressibility thermal effects cavitation. static pressure fluctuations during cavity oscillation cycles evaporation condensation processes are discussed detail. To predict high-pressure peaks bubble cloud collapses pulse propagation speed, real properties water mixture total energy conservation equation considered. In addition, estimated content undissolved air taken into account. validated means already published experiments or compared conducted authors, good agreement.

A Numerical Investigation of Unsteady Bubbly Cavitating Nozzle Flows

The effects of unsteady bubble dynamics on cavitating flow through a converging-diverging nozzle are investigated numerically. A continuum model that couples the Rayleigh–Plesset equation with the continuity and momentum equations is used to formulate unsteady, quasi-one-dimensional partial differential equations. Flow regimes studied include those where steady-state solutions exist, and those ...

Numerical and Experimental Investigation of Thermal Debinding

Powder injection molding (PIM) is an important netshape manufacturing process and has received much attention. One of the most critical steps in PIM process is debinding. It consumes a major part of the processing time. Failure of the powder compact often results if the process is accelerated. Thermal debinding is a common methodology for the final removal of residual polymer from a PIM compact...
