Mechanisms governing trace sodium capture by kaolinite in a downflow combustor
(1996)A 17-kW, 6-m-long gas-fired laboratory combustor was used to investigate the postflame reactive capture of trace sodium species by kaolinite. Emphasis was on alkali/sorbent interactions occurring in flue gas at temperatures ... -
Structural and electrical properties of antiferroelectric lead zirconate thin films prepared by reactive magnetron co-sputtering
(1997)The structural and electrical properties of antiferroelectric lead zirconate thin films were investigated. The films were prepared by a reactive magnetron co-sputtering method followed by rapid thermal annealing. The ... -
Wire Rope Selection for Manual Winch Application
(2009)The purpose of this paper is to demonstrate the application of analytical decision making during the selection of engineering entities in an engineering design setting. The paper develops a quantitative method for wire ... -
Effect of Minor Elements on the Fluidity of Secondary LM25 and LM27-Type Cast Alloys
(2009)In this study, the effect of individual and combined additions of Fe, Mn, Cr, Sr and Al-5Ti-1B grain refiner on the fluidity of secondary LM25 and LM27-type cast alloys was investigated. No change in fluidity was observed ... -
Temperature Profiles in a Wood Packed Bed Heated by Hot Inert Gases
(Mechanical Engineering Department, University of Nairobi, 1997)Presented in this paper are temperature profiles in a green-wood packed bed heated by hot inert gases for the sensible heating stage of wood carbonization. They give insight into the heat transfer during the initial ... -
Airflow maldistribution and the performance of a packaged air conditioning unit evaporator
(Department of Mechanical Engineering, University of NairobiSchool of Mechanical Engineering, University of Leeds, 2000)The performance of an evaporator for a packaged air conditioning unit has been investigated. A heat transfer program ACOL5 validated in an earlier study, was used to predict the performance. Non-uniform velocity distribution ... -
Environmental Monitoring and Management
(2013)A natural way to begin this monogram is by posing several pertinent questions. Firstly, what exactly does the term “monitoring” mean. Furthermore, is monitoring synonymous to measuring or observing? And more specifically, ... -
An Intrinsic Dislocation Density – Finite Element Formulation Of Metal Plasticity
(School of Mechanical, Manufacturing and Materials Engineering, Jomo Kenyatta University of Agriculture and TechnologySchool of Engineering, University of Nairobi, 2012)A computational model was developed to simulate elastic and plastic behavior in Body Centered Cubic (BCC) metals and alloys. The model provided for simultaneous simulation of the micro and macro length scales and used ... -
Selecting a Sampling Plan for Reinforcement Bars
(Department of Mechanical and Automotive Engineering. Technical University of MombasaDepartment of Mechanical Engineering. Jomo Kenyatta University of Agriculture and TechnologyDepartment of Mechanical Engineering. University of Nairobi, 2013)In this study we employ modern statistical methods to the sampling problem. The application of statistics by engineers dates back a long while in solving industrial, management, and research problems. Quality and ... -
Lathe stability charts via acoustic emission monitoring
(Department of Mechanical Engineering, Jomo Kenyatta University of Agriculture and TechnologyDepartment of Mechanical Engineering, University of Nairobi, 2001)Signal parameters characterizing acoustic emission (AE) detected during metal cutting have been theoretically correlated in a simple manner, to the work material properties, cutting conditions, and tool geometry. During ... -
