Similarity Analysis for Relativistic Flow in One Dimension
Transformations and restrictions are applied to the equations of relativistic flow in one space dimension which reduce the problem to a consideration of simpler differential equations. The results
Hidden Invariances in Problems of Two-Dimensional and Three-Dimensional Wall Jets for Newtonian and Non-Newtonian Fluids
A generating functions approach elaborated by Vinogradov enables one to derive conservation laws for the above-mentioned problems and, as a consequence, to find new self-similarities of the Navier--Stokes equations.

A one-dimensional piston problem of gasdynamics
This paper considers the case of a one-dimensional piston moving outwards with a speed proportional to rα and driving a strong shock into a non-uniform ambient gas whose density is initially
Properties of Solutions to Gas Dynamics Equations on a Rotating Plane: the Case of Motions with Uniform Deformation
A system of ideal polytropic gas equations written in the Lagrangian coordinates is considered on a uniformly rotating plane. For this system the first integrals corresponding to motions with uniform
Searching fundamental information in ordinary differential equations. Nondimensionalization technique
A formal protocol is proposed for applying the nondimensionalization process to ordinary differential equations, linear or not, leading to dimensionless normalized equations from which the resulting dimensionless groups have two inherent properties: they are physically interpreted as balances between counteracting quantities in the problem, and they are of the order of magnitude unity.
Scaling, Self-similarity, and Intermediate Asymptotics: Dimensional Analysis and Intermediate Asymptotics
Scaling laws reveal the fundamental property of phenomena, namely self-similarity - repeating in time and/or space - which substantially simplifies the mathematical modelling of the phenomena
Analytic solutions for the three-dimensional compressible Navier?Stokes equation
We investigate the three-dimensional compressible Navier–Stokes (NS) and the continuity equations in Cartesian coordinates for Newtonian fluids. The problem has an importance in different fields of
