An Analytic Approximation to the Isothermal Sphere
We present a useful analytic approximation to the solution of the Lane-Emden equation for infinite polytropic index the isothermal sphere. The optimized expression obtained for the density profile can be accurate to within 0.04% within 5 core-radii and to 0.1% within 10 core-radii.
متن کاملNon-Newtonian thermal convection of eyring-powell fluid from an isothermal sphere with biot number effects
This article investigates the nonlinear, steady boundary layer flow and heat transfer of an incompressible Eyring-Powell non-Newtonian fluid from an isothermal sphere with Biot number effects. The transformed conservation equations are solved numerically subject to physically appropriate boundary conditions using a second-order accurate implicit finite-difference Keller Box technique. The influ...
متن کاملSelf-lensing of a Singular Isothermal Sphere
Many astrophysical systems can be approximated as isothermal spheres. In an isothermal sphere, the “foreground” objects can act as lenses on “background” objects in the same distribution. We study gravitational lensing by a singular isothermal sphere analytically. Our results may have interesting applications. PACS numbers: 98.62.Sb, 95.30.Sf Typeset using REVTEX 1
متن کاملPolyharmonic Approximation on the Sphere
The purpose of this article is to provide new error estimates for a popular type of SBF approximation on the sphere: approximating by linear combinations of Green’s functions of polyharmonic differential operators. We show that the Lp approximation order for this kind of approximation is σ for functions having Lp smoothness σ (for σ up to the order of the underlying differential operator, just ...
متن کاملTransient Natural Convection Flow on an Isothermal Vertical Wall at High Prandtl Numbers: Second-Order Approximation
The method of matched asymptotic expansions, which has been used in previous studies of steady natural convection flow, is extended here to transient natural convection flow at high Prandtl number (Pr). Second-order expansion solutions, valid for large Prandtl numbers, are presented for the transient natural convection flow near a vertical surface which undergoes a step change in temperature. T...
