Approximate equivalence transformations and invariant solutions of a perturbed nonlinear wave equation
Autor: Ranis N. Ibragimov
Publikováno v: Electronic Journal of Differential Equations, Vol 2001, Iss 23, Pp 1-12 (2001)
We discuss the properties of a perturbed nonlinear wave equation whose coefficients depend on the first-order spatial derivatives. In particular, we obtain a group of transformations which are stable with respect to the given perturbation, and derive

On the tidal motion around the earth complicated by the circular geometry of the ocean's shape
Autor: Ranis N. Ibragimov
Publikováno v: Electronic Journal of Differential Equations, Vol 2000, Iss 35, Pp 1-11 (2000)
We study the Cauchy-Poisson free boundary problem on the stationary motion of a perfect incompressible fluid circulating around the Earth. The main goal is to find the inverse conformal mapping of the unknown free boundary in the hodograph plane onto

Energy Spectrum of Linear Internal Wave Field in the Vicinity of Continental Slope
Autor: Austin Biondi, Guang Lin, Sheng Zhang, Nathan Arndt, Ranis N. Ibragimov, Vesselin Vatchev, Maria Castillo
Publikováno v: Journal of Applied Mathematics and Physics. :2256-2274
The purpose of the research was to investigate two-dimensional modeling of efficiency of mixing, resulting from the reflection of a linear internal wave field (IWF) off a continental slope. Efficiency of deep ocean mixing was associated with the ener

Approximate and Invariant Solutions of a Mathematical Model Describing a Simple One-Dimensional Blood Flow of Variable Density
Autor: Ranis N. Ibragimov, Nail Ibragimov, Pirooz Mohazzabi
Publikováno v: Journal of Applied Mathematics and Physics. :1335-1354
We examine governing equations that could be used to model a one-dimensional blood flow within a pulsating elastic artery that is represented by a tube of varying cross-section. The model is considered from two perspectives. The first represents a si

Multidimensional wave fronts propagation along the beams associated with thermodynamic model of a rotating detonation engine
Autor: Ranis N. Ibragimov
Publikováno v: Applied Mathematical Modelling. 40:2661-2673
The main purpose here is to develop an analytic approach for investigating the wave front propagation on a surface of a cylinder that can be used as a descriptor of a detonation engine. The analysis is based on a weakly nonlinear approximated gas dyn

Conservation laws and invariant solutions of the non-linear governing equations associated with a thermodynamic model of a rotating detonation engines with Korobeinikov׳s chemical source term
Autor: Ranis N. Ibragimov, L. R. Galiakberova, Nail Ibragimov
Publikováno v: International Journal of Non-Linear Mechanics. 78:29-34
The non-linear governing gas dynamics equations that are used as a descriptor of a rotating detonation engine are investigated from the group theoretical standpoint. The equations incorporate approximation of Korobeinikov׳s chemical reaction model t

Splitting phenomenon of a higher-order shallow water theory associated with a longitudinal planetary waves
Autor: Ranis N. Ibragimov, Lin Guang
Publikováno v: Dynamics of Atmospheres and Oceans. 69:1-11
The Cauchy–Poisson free boundary problem associated with a nonstationary motion of a perfect incompressible fluid circulating around the equatorial plane of a planet is considered. It is shown that the corresponding theory of a higher-order shallow
