DESIGN OF SIX-STROKE INTERNAL COMBUSTION SPARK IGNITION ENGINE

ABSTRACTThe rate at which energy is lost by human activities is enormous. There is need to work on how to generate more energy and minimize the usage of the generated energy. In an internal combustion engine, there is need to focus on gaining energy usage by using generated heat during combustion process. To reduce the energy usage, emission rate and improve the efficiency of four-stroke internal combustion spark ignition engine, the four-stroke internal combustion spark ignition engine is mo...

Use of an exergetic approach to analyze the performance of a vapor compression refrigeration system using a refrigerant solution of a nanoparticle (TiO2), mineral oil, and R410a (base refrige

ABSTRACTThis project illustrates the use of an exergetic approach to analyze the performance of a vapor compression refrigeration system using a refrigerant solution of a nanoparticle (TiO2), mineral oil, and R410a (base refrigerant). Exergy investigation is a thermodynamics strategy which allows for the assessment and improvement of a refrigeration system in terms of efficiency and performance with basis placed on the 2nd law of thermodynamics. The primary objectives of this project are to e...

Generation of electrical power through Gas turbine.

The major components of a gas turbine are compressor, combustors, turbine and generator. It operates by continuous drawing in fresh air into the compressor. The Air is then compressed to a high pressure in the compressor and discharge into the combustion. Here the air is missed with gas and burns continuous once ignited to increase its energy level at constant pressure. The high pressure and temperature combustion product enters an expansion turbine that converts the gas thermal energy into m...

Effect of seawater corrosion on medium Carbon steel 0.34%C and 0.36%C

This project covers a study of the effect of seawater corrosion on 0.34% and 0.36% carbon steel compositions.Two (2) specimens (steel rods) of length 150mm (each) for both steel compositions were obtained. Out of each was gotten four (4) specimens of 10mm length, 10mm diameter and two (2) specimens of 50mm length, 10mm diameter. This yielded a total of twelve (12) samples. For each steel composition, one (1) specimen of 10mm length and one (1) specimen of 50mm length ...

Design and Construction of a Model Power Generating Windmill

This project covers the design and construction of a power generating windmill. The designs was carried out based on long-term available wind data of bida at 10m above the ground level. The average wind speed for Bida is 5.24m/s and rated turbine wind speed is 6.29m/s. The design of each components of the system were carefully constructed in a well equipped workshop within the school premises. Calculations were done manually for each components of the system and the results was match with the...

Design of Next Generation Civil and Military Aircraft with Ultra-High Bypass Engine using Composites, Advanced Materials and Technology

AbstractIndirect combustion noise had not been attracting research in the past, but recent indication seems to prove that it could be a threat in the future if not addressed. Means of reducing this type of noise to a low decibel value was also included. Noise is due to the ingestion of distorted atmospheric turbulence, as the two set of blades rotate in different direction. Open rotor noise is higher since the rotors are fully exposed to oncoming turbulence and lack ducting or a nacelle to at...

Design of Effective Solid Waste Management System: A Case Study of Ifite-Awka zone, Anambra State

Focuses on the maximum volume of waste generated in a particular month in a particular area and uses a heuristic model for it's analysis.Research ProblemA proper, efficient, reliable and hygienic waste handling and disposal technique tells more of our maintenance culture but the capacity and ability to efficiently manage the  waste  becomes inadequate.   The need   for this   study a rose because effective waste management is a tool for sustainable deve...

Performance Assessment of the Firefighting Personal Protective Tunic

ABSTRACTThis project centers on addressing the issue of the lack of research and development in Nigeria, in this case, looking into the firefighting and emergency sector. In this industry, the safety of the firefighters is of paramount importance as it is only then that they can fully carry out their duties and tasks. Of all the products that make up a complete assemble of the firefighters’ PPE, it is their personal protective tunic that was used for this project as it is the basic and most...

Design and Construction of a GSM-Controlled Pick and Place Robot

ABSTRACTThe modern manufacturing environment is dynamic and uncertain. In line with the globaltrend in manufacturing, this project is carried out to explore into the potentials of robots inmanufacturing, service industry, and domestic use. The robot was designed and constructed to incorporate the use of mobile phones as control mechanism via dual-tonemultiple frequency (DTMF). Various components such as the Gripper, Gears, Chains, and Control system were designed with good factor of safety...
