Analytic Approximate Solution for Falkner-Skan Equation [PDF]

open access: yesThe Scientific World Journal, 2014
This paper deals with the Falkner-Skan nonlinear differential equation. An analytic approximate technique, namely, optimal homotopy asymptotic method (OHAM), is employed to propose a procedure to solve a boundary-layer problem. Our method does not depend upon small parameters and provides us with a convenient way to optimally control the convergence of

Analytical solution approximation for bearing [PDF]

open access: yesAIP Conference Proceedings, 2017
The purpose of lubrication is to separate two surfaces sliding past each other with a film of some material which can be sheared without causing any damage to the surfaces. Reynolds equation is a basic equation for fluid lubrication which is applied in the bearing problem. This equation can be derived from Navier-Stokes equation and continuity equation.

Slowly rotating solution of quadratic gravity: An analytical approximation method

open access: yesNuclear Physics B, 2023
As we know, it is a nontrivial task to obtain analytical solutions for various gravitational theories. In this work, we obtain an analytical approximate rotating black hole solution for quadratic gravity (QG).

Approximate solutions for the skyrmion [PDF]

open access: yes, 2001
We reconsider the Euler-Lagrange equation for the Skyrme model in the hedgehog ansatz and study the analytical properties of the solitonic solution. In view of the lack of a closed form solution to the problem, we work on approximate analytical solutions.

New Approximations to Bond Prices in the Cox–Ingersoll–Ross Convergence Model with Dynamic Correlation

open access: yesMathematics, 2021
We study a particular case of a convergence model of interest rates. The bond prices are given as solutions of a parabolic partial differential equation and we consider different possibilities of approximating them, using approximate analytical solutions.

Energy-Based Criterion for Testing the Nonlinear Response Strength of Strong Nonlinear Oscillators

open access: yesJournal of Applied Sciences and Environmental Management, 2021
This article proposes a simple energy-based criterion developed to characterize four commonly identified responses, namely: linear, weakly nonlinear, moderately nonlinear and strongly nonlinear regimes.
