Approximations of the self-similar solution for a blastwave in a medium with power-law density variation
نویسنده
چکیده
Approximations of the Sedov self-similar solution for a strong point explosion in a medium with the power-law density distribution ρ ∝ r−m are reviewed and their accuracies are analyzed. The Taylor approximation is extended to cases m / = 0 and spherical, cylindrical and plane geometry. Two approximations of the solution are presented in the Lagrangian coordinates for all types of geometry. These approximations may be used for the investigation of the ionization structure of the adiabatic flow, e.g., inside adiabatic supernova remnants.

Approximations of the self-similar solution for blastwave in a medium with power-law density variation
Approximations of the Sedov self-similar solution for a strong point explosion in a medium with the power-law density distribution ρo ∝ r−m are reviewed and their accuracy are analyzed. Taylor approximation is extended to cases m 6= 0. Two approximations of the solution are presented in the Lagrangian coordinates for spherical, cylindrical and plane geometry. These approximations may be used fo...

In this study, a numerical examination of the significance of rotation and changeable gravitational field on the start of nanofluid convective movement in an anisotropic porous medium layer is shown. A model that accounts for the impact of Brownian diffusion and thermophoresis is used for nanofluid, while Darcy’s law is taken for the porous medium. The porous layer is subjected to uniform rotat...
متن کاملFrequency Analysis of FG Sandwich Rectangular Plates with a Four-Parameter Power-Law Distribution
An accurate solution procedure based on the three-dimensional elasticity theory for the free vibration analysis of Functionally Graded Sandwich (FGS) plates is presented. Since no assumptions on stresses and displacements have been employed, it can be applied to the free vibration analysis of plates with arbitrary thickness. The two-constituent FGS plate consists of ceramic and metal graded thr...
