Primary Resonance of van der Pol Oscillator under Fractional-Order Delayed Feedback and Forced Excitation

Shock and Vibration, 2017
The primary resonance of van der Pol oscillator under fractional-order delayed negative feedback and forced excitation is studied. Firstly, the approximate analytical solution is obtained based on the averaging method, and it could be found that the ...

1D Cahn-Hilliard equation: Ostwald ripening and modulated phase systems

, 2007
Using an approximate analytical solution of the Cahn-Hilliard equation describing the coalescence during a first order phase transition, we compute the characteristic time for one step of period doubling in Langer's self similar scenario for Ostwald ...

Approximate analytical solutions of MHD viscous flow

Journal of Naval Architecture and Marine Engineering, 2016
The paper presents the semi-numerical solution for the magnetohydrodynamic (MHD) viscous flow due to a shrinking sheet caused by boundary layer of an incompressible viscous flow. The governing three partial differential equations of momentum equations are reduced into ordinary differential equation (ODE) by using a classical similarity transformation ...
