Numerical Investigation of Bubble Cloud Dynamics in Shock Wave Lithotripsy
To provide greater understanding of some of the phenomena in Extracorporeal Shock Wave Lithotripsy (ESWL), we implemented a two-phase continuum model for cavitating flow and applied it to the simulation of bubble cloud dynamics in an electrohydraulic lithotripter. Through the combination of a WENO shock capturing scheme, curvilinear coordinates system and ensemble averaged mixture model, we com...
متن کاملShock wave focusing using geometrical shock dynamics
A finite-difference numerical method for geometrical shock dynamics has been developed based on the analogy between the nonlinear ray equations and the supersonic potential equation. The method has proven to be an efficient and inexpensive tool for approximately analyzing the focusing of weak shock waves, where complex nonlinear wave interactions occur over a large range of physical scales. The...
متن کاملNumerical Simulation of Shock-Wave/Boundary/Layer Interactions in a Hypersonic Compression Corner Flow
Numerical results are presented for the shock-boundary layer interactions in a hypersonic flow over a sharp leading edge compression corner. In this study, a second- order Godunov type scheme based on solving a Generalized Riemann Problem (GRP) at each cell interface is used to solve thin shear layer approximation of laminar Navier-Stokes (N-S) equations. The calculated flow-field shows general...
متن کاملInvestigation of focusing possibilities of convex and cylindrical phased arrays
This paper explores acoustic field simulation of 128 elements cylindrical phased array. The simulations were performed in a homogenous medium water at several frequencies from 2.25 MHz to 7.5 MHz. Beam width versus the focal distance with a different number of active elements for chosen focal distance is simulated. To determine focusing efficiency of the cylindrical array the beam width of the ...
متن کاملEstimation of Sloshing Wave Height in Broad Cylindrical Oil Storage Tanks Using Numerical Methods
Cylindrical steel tanks are important components of many industrial plants such as oil refineries and chemical plants. Usually failure of cylindrical tanks leads to serious consequences. During the past earthquakes such as 1964 Alaska and 1999 Turkey seismic performance of cylindrical tanks revealed that tanks are seismically vulnerable. Therefore, evaluation of seismic performance of these str...
