Research ArticleOpen accessIn the abstractWater Hammer Analysis by Characteristic MethodA.R. Lohrasbi, R. AttarnejadRapid changes in the velocity of fluid in closed conduits generate large pressure, which are transmitted through the system with the speed of sound. When the fluid medium is a liquid the pressure surges and related phenomena are described as water hammer. Water hammer is caused by normal operation of the system, such as valve opening or closure, pump starts … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 8,705 accessesView PDF Cite

Research ArticleOpen accessIn the abstractExperimental Investigation of Thermo-Physical Properties of Soil Using Solarisation TechnologyAhmed Abed Gatea Al-Shammary, Abbas Kouzani, Akif Kaynak et al.Soil Thermo-Physical Properties (TPP) depend on heat transfer in the soil. This paper presents a study on different soil solarisation technologies influenced by soil TPP. This study evaluates three factors: The tillage depth for soil at three levels (15, 25 and 45 cm), the number of plastic film at three levels (single, double and without plastic film) and three cases … …American Journal of Applied Sciences, Vol. 14, Issue 7 · 17 Jul 2017 · 7,963 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAssessment of Efficient Thermal Conversion Technologies and HHV from Compositional Characteristics of Cassava Peelings, Plantain Peelings and Corn CobsSamomssa Inna, Oumarou Amadou Amadou, Jiokap Nono Yvette et al.The understanding of compositional characteristics permits to predict the efficient thermal conversion technologies and Higher Heating Value (HHV). Although HHV can be determined directly, many models have been proposed for HHV prediction. They are based on proximate, ultimate, and structural analysis and require much data collected. The present work assesses to predict efficient thermal conversion technologies and HHV of the … …Energy Research Journal, Vol. 13, Issue 1 · 27 Dec 2022 · 10,160 accessesView PDF Cite
