Unconditionally positive finite difference and standard explicit finite difference schemes for power flow equation [PDF]
The University Thought: Publication in Natural Sciences, 2019 Power flow equation for step-index glass optical fiber was solved using recently reported unconditionally-positive finite difference (UPFD) scheme. Solution obtained using UPFD scheme was compared with solution obtained using standard explicit finite ...

A 2D Moving Mesh Finite Element Analysis of Heat Transfer in Arctic Soils
Thermo, 2023 Accurate soil heat transfer models are needed to predict and adapt to a warming arctic. A numerical model to accurately predict temperatures and thaw depths in soils, both with depth and with horizontal distance from features such as cliffs, was ...

A Robust Bubble Growth Solution Scheme for Implementation in CFD Analysis of Multiphase Flows
Computation, 2023 Although the full form of the Rayleigh–Plesset (RP) equation more accurately depicts the bubble behavior in a cavitating flow than its reduced form, it finds much less application than the latter in the computational fluid dynamic (CFD) simulation due to

Generalized finite-difference schemes [PDF]
Mathematics of Computation, 1969 Finite-difference schemes for initial boundary-value problems for partial differential equations lead to systems of equations which must be solved at each time step. Other methods also lead to systems of equations. We call a method a generalized finite-difference scheme if the matrix of coefficients of the system is sparse.

Finite differences in finite characteristic
Journal of Algebra, 2006 AbstractLet D be a Dedekind domain with characteristic p>0. In this paper, we are interested in the D-algebras Int[k](D) of integer-valued polynomials with all their k-first finite differences. Mainly, we describe the characteristic ideals Jn[k](D) of Int[k](D).

MethodsX, 2023 We consider two-parameter singularly perturbed problems of reaction-convection-diffusion type in one dimension. The convection coefficient and source term are discontinuous at a point in the domain.
