Turbulent flow inside a cylindrical baffled stirred vessel is studied experimentally for different Reynolds numbers. A set of speed was selected ranging from 100 rpm to 350 rpm. These speeds gave high turbulence but without significant surface vortex formation. Vector field’s maps and contours of time averaged velocities, for both radial and axial components in the impeller stream of a vessel stirred by a Rushton turbine, were determined by means of 2D PIV technique. This study reveals the importance of choosing the whole flow field of the entire vessel in order to provide comprehensive understanding of the flow pattern and mixing conditions which is essential for reliable design.

The Impact of Gasoline Subsidy Removal on the Transportation Sector in Nigeria

by Ismail O. Soile, Hezekiah Tsaku and Bilikisu Musa Yar'Adua

Original Research

Nigeria, like other oil exporting countries in the world has embarked on the policy of gradual removal of fuel subsidies since 1970s. However, this issue has become highly contentious in recent time due to the incessant nature and the effects on the economy.

Energy Management and Energy Crisis in Textile Finishing

by Faheem Uddin

Original Research

Textile industry is indeed one of the major energy consumers. Therefore, approaches introducing reduced energy processing of textiles in association with the standard energy management practices would be in obvious demand. Energy management standard is particularly desired for energy- intensive industrial sectors. Textile finishing organizations significantly depends upon the continual energy supply from fiber production to finished fabric. Textile processing areas that heavily consume water and electricity can be significantly improved in terms of reduced energy utilization and minimum energy loses through exercising improved housekeeping and standard management practices. It was perceived that ISO 50001 standard will provide management guideline and approaches to the textile sector organizations leading to an increased efficiency, reduced cost through less energy consumption, and improved energy performance. Any scientific information and data on hot air, heat, steam and processed water recycling available in literature would indeed be beneficial to enhance textile processing and finishing industry in the utilization of energy management policy, performance and efficiency measures, physical structure. The important factors that would be influenced by the energy management standard in textile finishing, ranging over fiber processing, pre- treatments, dyeing, printing, and special effects, are identified for improvement and discussed in this paper.

Experimental Research of Heat Transfer in Cooling Tower

by I. M. Kuzmenko

Original Research

Heat transfer coefficient for cooling tower is determined experimentally and theoretically, the latent heat and air flow heat to are calculated. Thickness of heat layer is calculated and is then compared to theoretically calculated the displacement layer. The heat transfer coefficient is calculated based on the values of displacement layer and its deviation from theoretically calculated one is up to 3 times in the range of air velocity of 1.3-3.0 m/s. The difference in temperature of the air and water film is calculated.
