Design of a mechanical cleaning device PIG (pipeline intervention gadget) connecting two transfer lines in Zimbabwe
(2016-09)In the Oil and Gas Industry, maintenance is done using a device or tool called a pig, chiefly to remove solids, dirt, and liquids from the pipelines. The aim of this work is to design and retrofit a pig which will clean 3 ... -
Design of a paper slitting and rewinding machine for a developing country, Zimbabwe
(2016-09)This paper is on the design of a paper slitting and rewinding machine for a developing economy which targets small to medium enterprises (SMEs). The current problem is the high cost of such machines on the market hence ... -
Knowledge Retention and Stabilisation within OPRAG: A Management must for the Excellence achievement.
(2016-09)Operations consist of the jobs or tasks composed of one or more elements or subtasks, performed typically in one location, whereby resource or data inputs are transformed onwards into desired goods, services, or results, ... -
Improving the management of operations at the “Office des Ports et RAdes du Gabon” (OPRAG): The road to achieve and sustain quality service delivery
(2016-09)The industrial engineering development in the spite of globalisation and fast technological advancement has set an unprecedented challenge for business around the world. Hence, new business models and concepts came to life ... -
To design and implement a reliable sugar evaporation control system that will work in an energy saving way
(2015)The main objective of this research was to deve1lop and implement a user friendly but advanced control program that is easy to monitor, control, maintain and implementing changes or correcting errors. There was also need ... -
Design of a crushing system that improves the crushing efficiency of gold ore at a local mine: Case of Zimbabwe
(2015)Mining involves a number of processes which are useful in gold extraction. The processes involved are gravity concentrations, flotation, etc. are available for the extraction of gold metal from its ores. The common processes ... -
Design of a small scale cereal packaging machine suitable for developing countries
(2015)Many food shortages which are being encountered in developing countries are due to lack of effective packaging which results in food loss. Packaging machines manufactured in developed countries are highly automated which ... -
Investigation of the physical and chemical stability of biodiesel produced from Jatropha Curcas Species in Zimbabwe
(Zimbabwe Institution of Engineers, 2016-02)Jatropha curcas L. seeds as a raw material for biodiesel production are a rapidly growing interest over the world because of their high oil content, ecological adaptability, and excellent fuel properties. Though there is ... -
A procedure for sizing pump-pipe systems with regard to minimising life cycle costs manageable on excel spreadsheets
(Zimbabwe Institution of Engineers, 2016-02)Pump-pipeline systems are a common feature of every industry and account for about 20% of the world’s electrical energy demand. Pump and pipe selection should happen simultaneously in pump-pipe system design rather than ... -
Mechanical thermal stresses and creep analysis of boiler tubes
(Zimbabwe Institution of Engineers, 2016-02)The boiler tubes are operated continuously at high temperature and pressure. Hence at high pressure for forces acting on the boiler tubes will be high. This research paper focuses on the analysis of one of the long term ... -
Improved flood estimation model for bridge and culvert design in Zimbabwe
(Zimbabwe Institution of Engineers, 2016-02)Economics and risk minimization in the design of infrastructure that is vulnerable to flood damage often prove to be non-commensurate objectives. To economically minimize the risk of hydraulic failure of this type of ... -
Design of a vehicle door structure based on finite element method.
(2014)The performance of door assembly is very significant for the vehicle design. In the present paper, the finite element method is used in the development processes of the door assembly. The stiffness, strength, modal ... -
Elasto-Plastic collapse analysis of pipe bends using finite element analysis
(2014)When an external load is applied to one of its ends, a pipe’s bends cross section tends to deform significantly both in and out of its end plane. This shell type behaviour characteristic of pipe bends and mainly due to ... -
Finite element analysis of ROM silo subjected to 5000 tons monotonic loads at an anonymous mine in Zimbabwe
(International Institute of Engineers, 2014-07)This paper introduces finite element analysis of Run off Mine (ROM) silo subjected to dynamic loading. The proposed procedure is based on the use of theoretical equations to come up with pressure and forces1 exerted by ... -
Water insecurity in Zimbabwe’s towns and cities: Challenge for institutions
(Zimbabwe Institution of Engineers, 2014-11)There is widespread concern over water insecurity in most towns and cities in Zimbabwe. Some households have gone for years without receiving water yet most reservoirs supplying such towns or cities have been recording ... -
The spatio-temporal variation of the 2014 Tokwe-Mukosi floods: a GIS and remote sensing based approach
(Zimbabwe Institution of Engineers, 2014-11)Floods are natural hazards that have always created an unexpected threat to human life and property. When severe floods occur in areas occupied by humans, they can create natural disasters that involve the loss of human ... -
Modelling and simulation of a dump truck tipping mechanism using EdenLISP
(Zimbabwe Institution of Engineers, 2013-12)The application and use of EdenLISP in mechanism design and analysis is demonstrated on the tipping mechanism of a dump truck. The foundation for mechanical engineering design is centred on mechanisms, their design operation ... -
Implementing Zimbabwean projects in the Zambezi Valley
(Zimbabwe Institution of Engineers, 2013-12)Projects such as the Kazungula-Kasane Bridge, Victoria Falls North Bank Power Station, Hwange 7 and 8 Thermal Power Station Extension, Batoka Gorge Hydro-electric Scheme, Zambezi-Bulawayo Water Supply Scheme, Devil's Gorge ... -
Effects of Plasma cutting on surface integrity of mild steel
(Zimbabwe Institution of Engineers, 2013-12)Persistent fatigue failure observed in vibrating screen side plates motivated this investigation to determine the effects of plasma cutting on the surface integrity and hence fatigue performance of mild steel plates. ... -
Machinery maintenance yesterday, today and tomorrow in the manufacturing sector
(International Association of Engineers (IAENG), 2015-07)Maintenance is what is done in machinery to prevent failure or breakdown. In ancient times no proper planning was carried out to do maintenance with the idea behind being simple machines and easy to control. As time ...
