Investigating Turbulent Convection in a Rectangular Enclosure Using Shear Stress Transport KΩ Model
(Kenyatta University, 2020)Studies have been done on the aspect ratio effect on natural convection turbulence using standard kε model but further studies showed that kω SST model performed better than both kε and kω model in the whole enclosure. ... 
A Numerical Study of Turbulent Natural Convection in a Rectangular Enclosure with Localised Heating and Cooling
(Kenyatta University, 201908)This study models natural turbulent convection in a rectangular enclosure with localized heating and cooling. The equations used in modeling the flow are the equation of continuity, momentum equation and the energy equation. ... 
Triple System and Fano Plane Structure in Z∗n
(Kenyatta University, 2020)A triple system is an absolutely fascinating concept in projective geometry. This project is an extension of previously done work on triple systems, specifically the triples that fit into a Fano plane and the (i, j, k) ... 
The Action of Symmetry Groups of Platonic Solids on their Respective Vertices
(Kenyatta University, 2020)Platonic solids are 3dimensional regular, convex polyhedrons. Each of the faces are equidistant and equiangular to each other in any of the solids. They derive their name from the ancient Greek philosopher, P lato who ... 
Numerical Simulation of Turbulent Natural Convection and Heat Transfer in a Rectangular Enclosure Using the 𝒌� − 𝝎� Model
(Kenyatta University, 2020)Turbulent flow is a type of fluid flow in which the fluid undergoes irregular fluctuations. The velocity of the fluid at a point is continuously undergoing changes in both magnitude and direction. Turbulent natural ... 
Mathematical Modeling of Tuberculosis Dynamics With Hygiene Consciousness as a Control Strategy
