Ali et al.Problem statement: The objective of this study was to identify, analyze and build the force equation that involved the velocity, acceleration, angle and distance at the ankle when making the instep kick. Approach: One subject which is a male national soccer player had been chosen as a subject for the study. The subject was selected from professional soccer player with … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 8,474 accessesView PDFCite
Research ArticleOpen accessIn the abstractHigh Temperature Convective Drying of a Packed Bed with Humid Air at Different HumiditiesJ. Sghaier, S. Messai, D. Lecomte, A. BelghithProblem statement: Drying a packed bed of porous particle at high temperature with varying humidity of hot air is an attractive process. Many researches on experimental and simulation on a fixed bed drying at low and average temperature are proposed. Few studies showed drying at high temperature with humid air or using superheated steam. The latest is compared to dry … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,023 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Pulsating Circular Hot Air Jet Frequencies on Local and Average Nusselt NumberRozli Zulkifli, Kamaruzzaman Sopian, Shahrir Abdullah, Mohd Sobri TakriffThe study was carried out to determine the effect of pulsating frequencies on the local and average heat transfer characteristic of a heated circular air jet. The velocity profile of a heated circular pulsating air jet was measured in the first part of the study. The same set-up was used to measure the heat flux of the pulsating jet impinging … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 7,500 accessesView PDFCite
Research ArticleOpen accessIn the abstractImprovement of the Vertical Dispersion of Pollutants Resulting From Chimneys by Thermosiphon EffectA. O.M. Mahmoud, J. Zinoubi, R. B. Maad, A. BelghithThe dispersion of pollutants, resulting from industrial chimneys, in the surrounding atmosphere made the interest in realizing emitting conditions appears. It also encourages the vertical dispersion of these pollutants. At a given wind velocity, the height of this dispersion is essentially a function of the thermal power and the flow rate at the chimney exit. To improve these qualities, we … …American Journal of Environmental Sciences, Vol. 2, Issue 2 · 30 Jun 2006 · 7,406 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Analysis of the Integration of Wind Turbines into the Design of the Built EnvironmentHassam Nasarullah Chaudhry, John Kaiser Calautit, Ben Richard HughesThe effect of wind distribution on the architectural domain of the Bahrain Trade Centre was numerically analysed using Computational Fluid Dynamics (CFD). Using the numerical data, the power generation potential of the building integrated wind turbines was determined in response to the prevailing wind direction. Simulating a reference wind speed of 6 m/s, the findings from the study quantified an … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 4 · 22 Dec 2014 · 7,534 accessesView PDFCite
