dc.description.abstract | Implementation of a new vectorized high-order accuracy numerical method for solving gravitational gas dynamics equations on supercomputers equipped with Intel Xeon Phi accelerators is presented in the paper. Combination of the Godunov method, the Harten-Lax-Van Leer method and the piecewise parabolic method on local stencil is at the basis of the method, that allows achieving high-order accuracy for smooth solutions and low dissipation on discontinuities. Chemokinetic model of formaldehyde formation based on molecular hydrogen and carbon monoxide is presented. Numerical experiment results, which describe the mechanism of formaldehyde formation based on reactions involving molecular hydrogen and carbon monoxide during a collision of di erent types of galaxies, are shown. | ru |
