Research ArticleOpen accessIn the abstractApplied a Closed-Loop Oscillating Heat-Pipe Heat Exchanger to Increasing Oil Yield in Pyrolysis ProcessN. Panyoyai, T. Wongsiriamnuay, S. SangsrichanProblem statement: A Closed-Loop Oscillating Heat-Pipe (CLOHP) heat exchanger was a heat exchanger with one of the most promising conductivity capacities because of its higher cooling and condensing potential. Therefore, the aims of this study were to design and fabricate a CLOHP to be applied to increasing oil yield in the pyrolysis process. Approach: Two types of oscillating heat-pipe arrangements-parallel … …Energy Research Journal, Vol. 1, Issue 1 · 30 Jun 2010 · 7,623 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Heat Transport in a Proton Exchange Membrane (PEM) Fuel CellE. Afshari, S.A. JazayeriIn this study a two-phases, single-domain and non-isothermal model of a Proton Exchange Membrane (PEM) fuel cell has been studied to investigate thermal management effects on fuel cell performance. A set of governing equations, conservation of mass, momentum, species, energy and charge for gas diffusion layers, catalyst layers and the membrane regions are considered. These equations are solved numerically in … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,343 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesalination of Saline Sludges Using Ion-Exchange Column with ZeoliteA.E. Ghaly, M. VermaA flushing process followed by a zeolite based ion-exchange process were developed for the treatment of saline sludges from oil and gas exploration sites. The particle size distribution of sludge sample indicated the presence of very fine sand and clay. The electrical conductivity of the sludge was 42.2 dS m-1 indicating very saline sludge and the Cation Exchange Capacity (CEC) … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 7,067 accessesView PDFCite
Research ArticleOpen accessIn the abstractEmission of Nitrogen Dioxide from Butane Gas Heaters and Stoves IndoorsMarwan Ghosn, Roula Flouty, Najat A. SalibaLevels of indoor nitrogen dioxide (NO2) in a home equipped with butane gas stove and heaters are reported between the months of February and July 2003.
