Magma flow through elastic-walled dikes [PDF]
, 2005 A convection–diffusion model for the averaged flow of a viscous, incompressible magma through an elastic medium is considered. The magma flows through a dike from a magma reservoir to the Earth’s surface; only changes in dike width and velocity over ...

Numerical Study on the Non-Oscillatory Unstarted Flow in a Scramjet Inlet-Isolator Model
Aerospace, 2022 For successful scramjet engine operations, it is important to understand the mechanism of the inlet unstart phenomenon. Among various unstarted flow patterns in hypersonic inlets, the mechanism of low-amplitude oscillatory unstarted flow is still unclear.

Choking conditions for nonuniform viscous flows [PDF]
Physics of Fluids A: Fluid Dynamics, 1993 The laminar viscous compressible flow of a gas in a pipe of -*constant cross section joining two reservoirs is considered. As it is well known, the pipe flow becomes independent of the discharge pressure if this is lower than a critical value. Then it is found that the parabolic equations describing the high Reynolds number flow in the interior of the ...

Off-Design Analysis Method for Compressor Fouling Fault Diagnosis of Helicopter Turboshaft Engine
Modelling, 2023 Fouling, caused by the adhesion of fine materials to the blades of the compressor’s last stages, changes the airfoil’s shape and function and the inlet flow angle on the blades.

Compressible and Choked Flows in Rotating Passages [PDF]
Open Journal of Fluid Dynamics, 2019 The present study revisits the rotating duct problem examined by Polihronov and Straatman (J. Polihronov and A. G. Straatman, Phys. Rev. Lett. v. 109, p. 054504 (2012)). Starting from the general compressible Euler equations in a non-stationary reference frame closed form expressions for velocity, temperature, density and pressure along the duct are ...

Physics of two-phase flow: choked flow [PDF]
, 1981 It is shown that the basic equations governing the flow of a two-phase fluid, i.e., liquid and vapor, are natural extensions of those equations that describe single-phase flow. The exact form of the equations depends on the particular assumptions used to characterize the two-phase flow, i.e., the equations depend on the model chosen.

Numerical investigation of the acceleration performance of a thermally choked ram accelerator
Advances in Mechanical Engineering, 2015 The flow fields of the thermally choked mode of ram accelerators were studied numerically. The goal of this study was to investigate the effects of the gas reaction rate, the velocity and the projectile shapes on the performances of ram accelerators. The
