Numerical experiment with upstream boundary conditions
EPJ Web of Conferences, 2012 The work deals with a numerical solution of subsonic and transonic flows described by the system of Euler equations in 2D and 3D flows in a channel. Authors used Lax-Wendroff and the multistage Runge-Kutta scheme to numerically solve the flows in a 2D G AMM

Loss Analysis of a Transonic Rotor with a Differential Approach to Entropy Generation
Machines, 2023 The loss mechanism of transonic axial compressors is a long-standing problem that involves almost all types of entropy generation in fluid flows, such as skin friction, shock waves, shear flows, corner separation, and tip vortices.

Calculation of transonic flows around profiles with blunt and angled leading edges
Vietnam Journal of Mechanics, 2016 Transonic flow is a mixed flow of subsonic and supersonic regions. Because of this mixture, the solution of transonic flow problems is obtained only when solving the differential equations of motion with special treatments for the transition from ...

Effect of Levels of Fidelity on Steady Aerodynamic and Static Aeroelastic Computations
Aerospace, 2020 Static aeroelastic deformations are nowadays considered as early as in the preliminary aircraft design stage, where low-fidelity linear aerodynamic modeling is favored because of its low computational cost.

Application of a fast transonic trajectory determination approach in 1-D modelling of steady-state two-phase carbon dioxide flow [PDF]
E3S Web of Conferences, 2019 An original generalised procedure of determination of the transonic trajectory has been proposed. The procedure is much faster than the commonly used Newton Critical Point approach.

Smooth Transonic Flows Around Cones
Networks and Heterogeneous Media, 2022 <p style='text-indent:20px;'>We consider a conical body facing a supersonic stream of air at a uniform velocity. When the opening angle of the obstacle cone is small, the conical shock wave is attached to the vertex. Under the assumption of self-similarity for irrotational motions, the Euler system is transformed into the nonlinear ODE system. We
