Design of Solar Powered Vapour Absorption System
Over the past few decades, energy is the backbone of technology and economic development. In addition to men, machines and money, ‘energy’ is now the fourth factor of Continue reading
Renewable Energy for Rural Electrification and Development in Mozambique
Rural areas continue to be home to the majority of the population in Africa. The importance of providing modern energy to rural areas cannot, therefore, be overemphasized. No wonder that at presently the major energy resource in Continue reading
Model Based Evaluation of UEGO Performance and Sensitivity
Closed loop fuel injection have been in use for two decades but it’s not until the recent five years that the wide band lambda sensor have been utilized. The goal is to explain wide band and discrete lambda sensors in a Continue reading
Multi-body dynamics in full-vehicle handling analysis
This paper presents a multidegrees-of-freedom non-linear multibody dynamic model of a vehicle, comprising front and rear suspensions, steering system, road wheels, tyres and vehicle inertia. The model incorporates all sources of Continue reading
Design of 120cc Single Cylinder Experimental Engine for Analysis of Intake Swirl and Multiple Ignition Sites
The intent of this study is to design, build, and test a cylinder head with variable swirl and ignition sites. The design aspect used Solid Works Floworks to model airflow within the head and cylinder. Swirl rate and volumetric flow rate were calculated from the results. Many design iterations took place before a Continue reading
On Mathematical Modeling of Shaped Charge Penetration
Shaped charges are a well established type of projectile, subjected to a lot of research ever since emerging as a viable technology in the 1940s. The penetration achieved by shaped charges decreases with Continue reading
A Model on How to Use Field Data to Improve Product Design: a Case Study
To stay competitive, companies are forced to improve their products continuously. Field data is a source of information that shows the actual performance of products during operation, and that information can be Continue reading
3D Fuel Tank Models for System Simulation
ABSTRACT
The purpose of the present master thesis is to optimize the current fuel tank simulations procedure for the next generation of JAS 39 Gripen ghters developed by SAAB AB. The current simulation process involves three different steps performed in Continue reading
Computer Aided Design of Side Actions for Injection Molding of Complex Parts
Often complex molded parts include undercuts, patches on the part boundaries that are not accessible along the main mold opening directions. Undercuts are molded by incorporating side actions in the molds. Side actions are mold pieces that are Continue reading
The Development of a Vacuum Forming System for KYDEX® and other Thermoplastic Sheet
ABSTRACT
Vacuum forming is a popular, cost effective method amongst large and small scale applications. The method is used to mold a material to the surface Continue reading
