Shockwaves in Converging Geometries
Plate impact experiments are a powerful tool in equation of state (EOS) development, but are inherently limited by the range of impact velocities accessible to the gun. In an effort to dramatically increase the range of pressures which can be studied with available impact velocities, a new experimental technique is being developed. The possibility of using a confined converging target to focus ...
متن کاملShockWaves in Plane Symmetric Spacetimes
We consider Einstein’s equations coupled to the Euler equations in plane symmetry, with compact spatial slices and constant mean curvature time. We show that for a wide variety of equations of state and a large class of initial data, classical solutions break down in finite time. The key mathematical result is a new theorem on the breakdown of solutions of systems of balance laws. We also show ...
متن کاملArtificial Surface Tension to Stabilize Captured Shockwaves
Computationally captured shockwaves, especially at very high Mach number, often display anomalous behavior not encountered in nature. Figure 1 shows three of the most notorious examples. The passage of a normal shock over a slightly perturbed mesh was observed to be unstable by Quirk. However, it was subsequently discovered that neither the mesh perturbation nor the shock motion was always need...
متن کاملProbing mechanobiology with laser- induced shockwaves
Traumatic Brain Injury (TBI) occurs when an external force injures the brain. While clinical outcomes of TBI can vary widely in severity, few mechanisms of neurodegeneration following TBI have been identified for treatment. We propose a model for studying TBI using laser-induced shockwaves (LISs). An optical system was developed that allows single cells to be studied in response to LISs. Our sy...
متن کاملShockwaves and Local Hydrodynamics; Failure of the Navier-stokes Equations
Abstract Shockwaves provide a useful and rewarding route to the nonequilibrium properties of simple fluids far from equilibrium. For simplicity, we study a strong shockwave in a dense two-dimensional fluid. Here, our study of nonlinear transport properties makes plain the connection between the observed local hydrodynamic variables (like the various gradients and fluxes) and the chosen recipes ...
