Computational challenges for simulations related to the NASA electric arc shock tube (EAST) experiments

TL;DR: In this article, an axisymmetric viscous shock tube simulation code is developed that keeps the shock and the contact discontinuity stationary in suitably constructed moving frames of reference, and the flowfield aroun...

TL;DR: In this article, the authors assess the current computational capability in simulating time-accurate unsteady nonequilibrium flows in the presence of strong shock waves with state-of-the-art physical models.

TL;DR: In this paper, a high-fidelity collisional-radiative (CR) model for laser-plasma interaction is presented, which is based on a finite volume discretization with high-order reconstruction procedure and a multi-stage time integration method.

TL;DR: In this article , a quasi-one-dimensional analytical methodology for predicting the nonuniformities in the post-shock test gas based exclusively on the experimentally measured history of shock speed down the tube is presented.

TL;DR: In this paper, an approach which closely maintains the non-dissipative nature of classical fourth or higher-order spatial differencing away from shock waves and steep gradient regions while being capable of accurately capturing discontinuities, steep gradient, and fine scale turbulent structures in a stable and efficient manner is described.

TL;DR: In this article, the notion of subcell resolution is introduced, which is based on the observation that unlike point values, cell-averages of a discontinuous piecewise-smooth function contain information about the exact location of the discontinuity within the cell.

TL;DR: The “built-in” de-aliasing property of the discretized skew-symmetric form for the non-linear terms of the Navier?Stokes equations is taken as a starting point and it is confirmed that the use of a high-order scheme improves the results, even in this type of steady applications.
