Simulating Pressure Distribution of a Horizontal Well in an oil Reservoir Subject to Single Edged and Bottom Constant Pressure
(Kenyatta University, 2022)In this study the pressure distribution in an oil reservoir with a horizontal well is investigated. A horizontal well with single-edged and constant bottom pressure is outlined. A reservoir bounded with two constant pressure ... -
Phytochemical Analysis, Anti-Inflammatory Activity, Antioxidant Activity and Toxic Effects of Aqueous Root Extract of Launaea CORNUTA (Hochst. Ex Oliv. & Hiern.) Evans Kapanat Akimat (Bs.C)
(Kenyatta University, 2022)Anti-inflammatory, anti-nociceptive and antioxidant drugs have alleviated the agony of millions of people, especially in the developing countries where management of inflammation remains a big challenge. Nonetheless, despite ... -
Numerical Analysis of the Thermophysical Properties of Hybrid Nanofluids for Industrial Use
(Kenyatta University, 2022)Hybrid nanofluids engineered using two or more different types of nanoparticles suspended in the base fluid have numerous industrial and engineering applications. The applications range from heat transfer (coolant) fluids ... -
