概要

• 論文の詳細を見る

• A mechanism of enstrophy generation is investigated numerically in a shock-dominated turbu-fence driven by a random external force which has only the compressible component. Enstrophyis generated, especially on collision of shock, as a pair of vortex tube of opposite sense of rotationbehind curved shocks. The roles of various terms in enstrophy equation are clarified in enstrophygeneration process. Generation of enstrophy is enhanced by strong alignment of each term ofthe enstrophy equation with the vorticity vector.
