Computational fluid dynamics simulations using the WENO method and level set method are applied to high Mach number nonrelativistic astrophysical jets, including the effects of radiative cooling. WENO methods introduced in Liu et al. (J. Comput. Phys., 115:200–212, 1994) have allowed us to simulate HH 1-2 astrophysical jets at Mach number much higher than Mach 80 (Ha et al. in J. Sci. Comput. 2...

Abstract Planetary bow shocks are a natural laboratory for investigating the physics of collisionless shocks. Given that spacecraft observations provide us with information regarding temporal structure shock, often multi‐spacecraft missions and kinetic simulations needed to discern nature dissipation processes at shock resulting spatial structure. Such an approach through ISEE mission 1.5‐D hyb...

We introduce a low Mach number equation set for the large-scale numerical simulation of carbon-oxygen white dwarfs experiencing a thermonuclear defla-gration. Since most of the interesting physics in a Type Ia supernova transpires at Mach numbers from 0.01 to 0.1, such an approach enables both a considerable increase in accuracy and savings in computer time compared with frequently used compres...
