The validity of the reduced order [Delale and Pasinlioglu, “Acoustic cavitation model based on a novel gas pressure law,” AIP Adv. 11, 115309 (2021)] classical polytropic laws during response bubble to variations in surrounding liquid is investigated. In particular, from exact expression coupled thermal behavior bubbles, we identify conditions where law hold. We then distinguish three regimes for change state its nonlinear oscillations as nearly isothermal, transition, adiabatic regimes,...
In this paper, we study a general class of nonlocal nonlinear coupled wave equations that includes the convolution operation with kernel functions. For appropriate selections functions, system becomes well-known equations, for instance Toda lattice system, improved Boussinesq equations. A numerical scheme is proposed solitary solutions using Pethiashvili method. Using different kernels, validity method has been tested.

The thermal behaviour of a spherical gas bubble in liquid driven by an acoustic pressure is investigated the uniform approximation employing iterative method to solve energy balance equations between and surrounding for temperature distribution inside bubble. It shown that first solution leads order law as polytropic power wall radius, with index given explicit function isentropic exponent gas. resulting reduces classical isothermal adiabatic laws appropriate limits. then applied...
The thermal behavior of a spherical gas bubble in liquid excited by an acoustic pressure signal is investigated constructing iterative solution the energy balance equations between and surrounding uniform approximation. This leads to hierarchy for radial partial derivatives temperature at wall, which control temporal rate change within bubble. In particular, closure relation introduced based on ansatz that approximates rapid state during collapse from almost isothermal adiabatic time...
Bu çalışmanın amacı, deney sonuçlarıyla uyumlu ve ticari yazılımlara uyarlanabilen bir hidrodinamik kavitasyon modelinin geliştirilmesidir. Bunun için sanki-bir-boyutlu kabarcıklı kavitasyonlu lüle akışları yeni kabarcık gaz basıncı yasası kullanılarak sönüm mekanizmalarını içerecek şekilde modeli geliştirilmiştir. modelde sıvı iki-fazlı homojen karışım olarak ele alınmış, dinamiği Rayleigh-Plesset denklemi kullanılmış çekirdekleşmesi göz önünde bulundurulmamıştır. Böylece elde edilen...
