Benchmarking solutions of the Folgar–Tucker-Equation and its reduction to a linear problem for non-linear closure forms

چکیده
The Folger–Tucker-Equation (FTE) arises from a modification of the Jeffery equation and describes orientation elongated particles in flow by means tensor A. Though FTE represents most widespread commercially used relaxation for A simulations injection molding short-fiber reinforced fluids, analytical solutions formulation applied industry are hardly investigated. Previous work focused on solution underlying (modified) Jeffery’s its integration to rather than direct FTE. present paper firstly introduces lemma that reduces nonlinear formulations linear problems. Its is numerically computational less intensive one original Secondly, this presents benchmarking validate simulation algorithms. Thirdly, closer look at two dimensional enables deeper understanding mathematical behavior popular differential equation. influence rotational components velocity field process analyzed. Finally an extension three case discussed shortly.

15 صفحه اولa new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...

متن کاملExact and numerical solutions of linear and non-linear systems of fractional partial differential equations
The present study introduces a new technique of homotopy perturbation method for the solution of systems of fractional partial differential equations. The proposed scheme is based on Laplace transform and new homotopy perturbation methods. The fractional derivatives are considered in Caputo sense. To illustrate the ability and reliability of the method some examples are provided. The results ob...
متن کاملDifferential Transform Method to two-dimensional non-linear wave equation
In this paper, an analytic solution is presented using differential transform method (DTM) for a class of wave equation. The emphasis is on the nonlinear two-dimensional wave equation. The procedures introduced in this paper are in recursive forms which can be used to obtain the closed form of the solutions, if they are required. The method is tested on various examples, and the results reveal ...
