Simulation of transonic flutter and active shockwave control

L. Djayapertapa, C.B. Allen

Transonic flutter and active flap control, in two dimensions, are simulated by coupling independent structural dynamic and inviscid aerodynamic models, in the time domain. A…

Numerical study of active shock control for transonic aerodynamics

N. Qin, Y. Zhu, S.T. Shaw

In this paper, the effectiveness of a number of active devices for the control of shock waves on transonic aerofoils is investigated using numerical solutions of the…

Dynamic modeling in large‐eddy simulation of turbulent channel flow: Investigation of two‐dimensional versus three‐dimensional test filtering

Jessica Gullbrand

Large‐eddy simulation (LES) of a turbulent channel flow is performed using different subfilter‐scale (SFS) models and test filter functions. The SFS models used are the dynamic…

The role of endothermic gasification in propellant ignition

Caroline Lowe

This study explores a reactor model designed to describe the decomposition, ignition and combustion of energetic materials in combination with real experimental data for these…

Rarefied, superorbital flows in an expansion tube

V. Wheatley, H.S. Chiu, P.A. Jacobs, M.N. Macrossan, D.J. Mee, R.G. Morgan

This paper describes a free‐piston driven expansion tube and its instrumentation. The facility is used to generate rarefied flows at speeds of approximately 10 km/s. Although the…

Numerical simulation of inductively coupled plasma flows under chemical non‐equilibrium

Gérard Degrez, David Vanden Abeele, Paolo Barbante, Benot Bottin

This paper presents a detailed review of the numerical modeling of inductively coupled air plasmas under local thermodynamic equilibrium and under chemical non‐equilibrium. First…

Discretization of the magnetic field in MPD thrusters

Jörg Heiermann, Monika Auweter‐Kurtz

For the numerical simulation of magnetoplasmadynamic (MPD) self‐field thruster flow, the solution of one of the two dynamical Maxwell equations – Faraday's law – is required. The…
