Pressure-Velocity Coupling Schemes for Bouyancy Driven Flow in a Differentially Heated Cavity Using F.V.M and Matlab

Purity Mberia, Stephen Karanja & Mark Kimathi · Journal of Advances in Mathematics and Computer Science · 2021

Numerical analysis of fluid flow is anchored on the laws of conservation. A challenge in solving the momentum equation arises due to the unavailability of an explicit pressure equation. To avoid solving the pressure term most researchers have eliminated it by cross differentiatin...

Simulation of a Deterministic Model of HIV Transmission between Two Closed Patches

James Khobocha Mirgichan, Cyrus Gitonga Ngari & Stephen Karanja · Journal of Advances in Mathematics and Computer Science · 2020

Numerical simulation of a deterministic model of HIV transmission between major cities in Kenya is carried out. The model considered two closed patches connected by the commuter movements of truck drivers being the agents of HIV transmission. The transmission kernel being the fun...

A Theoretical Model of Corruption Using Modified Lotka Volterra Model: A Perspective of Interactions between Staff and Students

Mercy Kawira, Cyrus Gitonga Ngari & Stephen Karanja · Journal of Advances in Mathematics and Computer Science · 2020

Corruption is the misuse of power or resources for private gain. This undermines economic development, political stability, and government legitimacy, the society fabric, allocation of resources to sectors crucial for development, and encourages and perpetuates other illegal oppo...
