WebThe simulation of the flow evolution then necessitates the use of accurate and robust numerical methods. In 3D turbulent flows, where the number of degrees of freedom is greater than in high Re laminar flows, to get solutions it is necessary to introduce some sort of closure to account for the impossibility to resolve the small scales. Before ... WebThe convergence of the method is established and observed to be first-order convergent, but it is accelerated by Richardson extrapolation. To validate the applicability of the proposed method, some numerical examples are considered and observed that the numerical results confirm the agreement of the method with the theoretical results effectively.

WebA system of M(≥ 2) coupled singularly perturbed linear reaction–diffusion equations is considered on the unit square.Under certain hypotheses on the coupling, a maximum principle is established for the differential operator. The relationship between compatibility conditions at the corners of the square and the smoothness of the solution on the closed … WebAn implicit method is developed for the numerical solution of option pricing models where it is assumed that the underlying process is a jump diffusion. This method can be applied to a variety of contingent claim valuations, including American options, various kinds of exotic options, and models with uncertain volatility or transaction costs.
