Ishikawa-Collocation Method for Nonlinear Fredholm Equations with Non-Separable Kernels

Chinedu Nwaigwe & Azubuike Weli · Journal of Advances in Mathematics and Computer Science · 2023

A fixed point method is developed on a mesh for the solution of nonlinear Fredholm equation. First, the problem is collocated at mesh points and a second order quadrature rule is used to approximate the nonlinear integral. Under the assumption of nonexpansivity of self-map, we co...

Analytical Solution of a Non-isothermal Flow in Cylindrical Geometry

Chinedu Nwaigwe & Innocent Uchenna Amadi · Asian Research Journal of Mathematics · 2021

This study proposes analytical solution to the problem of transport in a Newtonian fluid within a cylindrical domain. The flow is assumed to be dominated along the channel axis, and is taken to be axi-symmetric. No-slip boundary condition is considered for velocity while the temp...

On Computational Efficiency of Nine Iterative Algorithms for Hammerstein Equations

Azubuike Weli & Chinedu Nwaigwe · Asian Research Journal of Mathematics · 2023

Many fixed point iterative methods have been proposed. Their authors provide, theoretically, the rate of convergence which indicates how much the error changes after one iteration step. Of practical importance are the CPU time required by each method and their accuracy. This has...

Effects of Viscosity and Magnetic Field on a Non-Isothermal Cylindrical Channel Flow

Roseline Ize. Ndu, Chinedu Nwaigwe & Amos Emeka · Journal of Advances in Mathematics and Computer Science · 2023

This study examines the effect of viscosity and magnetic field on a non-isothermal cylindrical channel flow.  This work considered a model of convective-thermal-diffusion with constant viscosity and magnetic field. The governing model equations are nondimensionalized using the di...
