natural convection in a porous medium with heat generation: self-similar solution
natural convection heat transfer from a vertical heated plate in a saturated porous medium is analyzed under thermal non-equilibrium assumptions. the plate is maintained at a non uniform temperature and the fluid is considered to be with internal heat generation. the coupled momentum and energy equations for fluid and solid phases are transformed to a similarity format, and solved numerically. ...
متن کاملA self-similar inhomogeneous dust cosmology
A detailed study of an inhomogeneous dust cosmology contained in a γ-law family of perfect-fluid metrics recently presented by Mars and Senovilla is performed. The metric is shown to be the most general orthogonally transitive, Abelian, G2 on S2 solution admitting an additional homothety such that the self-similar group H3 is of Bianchi type VI and the fluid flow is tangent to its orbits. The a...
متن کاملSelf-similar evolution of a precipitate in inhomogeneous elastic media
In this paper, we present linear theory and nonlinear simulations to study the self-similar growth and shrinkage of a precipitate in a 2D elastic media. This work is motivated by a series of studies by Li et al., where the existence and morphological stability of self-similarly evolving crystals were demonstrated in a diffusional field. Here, we extend the theory and simulations to account for ...
متن کاملApproximations 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...
متن کاملAnalytic-Approximate Solution For An Integro- Differential Equation Arising In Oscillating Magnetic Fields Using Homotopy Analysis Method
In this paper, we give an analytical approximate solution for an integro- differential equation which describes the charged particle motion for certain configurations of oscillating magnetic fields is considered. The homotopy analysis method (HAM) is used for solving this equation. Several examples are given to reconfirm the efficiency of these algorithms. The results of applying this procedure...
