Proper orthogonal decomposition of eigen modes in a gas affected by a mass force
Anna Perelomova, Sergey Leble
The relations connecting perturbations in acoustic and entropy modes in a gas affected by a constant mass force, are derived. The background temperature of a gas may vary in the di…
Sound velocity and acoustic nonlinearity parameter for fluids. Thermodynamic premises
Sergey Leble, Anna Perelomova, Magdalena Kusmirek-Ochrymiuk
New theoretical formulae of the sound velocity and the B/A nonlinearity parameter for some fluids are presented in the paper. Semi--ideal and van der Waals models of gas are consid…
Acoustic radiation force and streaming induced by non-periodic ultrasound
Anna Perelomova
Starting from the linear flow of homogeneous fluid, five modes are defined as eigenvectors of the basic system of conservation laws. Quasi-plane geometry is considered. Projectors…
Streaming Caused by Impulse Acoustic Wave
Anna Perelomova
Five eigenvectors of the linear thermoviscous flow over the homogeneous background derived for the quasi-plane geometry of the flow. The corresponding projectors are calculated and…
Tollmien-Shlichting and sound waves interaction: general description and nonlinear resonances
A. Perelomova, S. Leble
The general hydro-thermodynamic system of equations in 2+1 dimensions with arbitrary equations of state (Taylor series approximation) is split to eigen modes: Tollmienn-Schlichting…
