Item Development and preliminary performance evaluation of a solar collector for adsorption refrigerator(2009) Odesola, I. F.The design and construction of a flat plate solar collector is presented in this paper. The solar collector was designed to power adsorption refrigerator using activated carbon/methanol pair. Design was such as to provide simplicity and yet ruggedness for harsh operating environment in the tropical climate of Nigeria. For methanol desorption, the collector must reach a maximum temperature of at least 100°C. Performance results showed that the maximum temperature of 108°C attained in the solar collector was adequate for methanol generation, while maximum received insolation of 1000 kW/m2 was sufficient for methanol desorption.Item Development and evaluation of fluid mechanics laboratory curriculum: a case study of the University of Ibadan, Nigeria(2004) Odesola, I. F.; Salami, R. O.Mechanics in the University of Ibadan, Nigeria. The University has been equipped with standard laboratory for the Leaching of Fluid mechanics, but over the years some equipment have broken down and affected the leaching of Fluid Mechanics. All over the years the needs of the students have changed. This paper starts by reporting the rehabilitation and commissioning of one of the equipment. And then goes ahead to formulate the laboratory exercises required to be performed by the students in Fluid Mechanics before graduation in B.Sc degree programme bearing in mind the functionality of existing equipment and the environment awaiting the students on graduation. Several improvements have been made and documentation done. The paper concludes that in most first generation Universities in Nigeria, Fluid Mechanics laboratories are well equipped, but most of the equipment are not functioning because of minor elements that could have been improved and installed. It recommends that with little funding and commitment of staff and students this laboratory would be kept running to meet the need of Nigerian Engineering students.Item Design, fabrication and performance evaluation of a domestic dish washing machine(2012-03) Odesola, I. F.; Afolabi, O. A.Plate washing is a daily activity across the globe which involves a lot of energy to accomplish manually or mechanically. The objective of this work is to design and fabricate a dish washing machine that is efficient and easy to operate. Stainless steel and mild steel was used for the construction of the machine considering their availability, cost reduction and corrosion resistance. The motor used a power of 0.75hp (559.5 W), voltage of 240V and a speed of rotation of “1200 r.p.m” which was reduced to “100 r.p.m” using a reduction gear of velocity ratio (V.R) “12:1”, the shaft torque being “53.4 N-m”. The plates were washed and rinsed in a separate basin using a liquid detergent and clean water following appropriate measure per cycle. Detailed design drawings of all the machine parts were drawn using AutoCAD. The performance analysis of the machine shows that the number of plates washed and the time taken were 20 plates per minute (1min), 5 plates per minute for the machine and manual operation respectively. The capacity of the machine is 20 plates per minute (1880 per hour). The machine washes plates without breakages.Item Design, construction and performance evaluation of a commercial ice-maker(2006) Odesola, I. F.; Nwaneto, F. N.; Adeyemo, A. S.The ice-maker (freezer) was designed, constructed and tested. The ice-making machine is to freeze 27kg of water in 9 different compartments in 12 hrs. The quantity of heat to be removed in order to achieve freezing is 12556.89 kJ and this is used to determine the refrigeration tonnage of the machine (0.124 ton). Polyurethane and Galvanized steel sheets have been selected for insulation and cabinet materials respectively due to their low thermal conductivities and high corrosion resistant properties. The performance tests show that the ice-maker is capable of producing 9 ice cubes (10 cm x 10 cm x 30 cm) in 12 hrs; while the economic analysis indicate that the project iseconomically viable. The cost of the ice-maker is N 51,650.00 and the investment payback is estimated to be 74 days with regular supply of electricity.Item Computerized approach to cooling load estimates for air-conditioning design(2006) Odesola, I. F.; Sefiu, Y. B.The research work provides the basic information for the design of a Central Air-Conditioning system for Kenneth Dike Library extension, University of Ibadan, Oyo State used as a case study. The software was designed, using a visual basic 6.0 (C++) programming language, to perform a thermal analysis for all the rooms of the floors in the building. The developed software called AIRCCAD is implemented to handle mathematical equations and engineering calculations efficiently and effectively and provide more accurate information at the very shortest possible time than manually calculated design.
