Research ArticleOpen accessEvery word in the titleVariable Viscosity, Chemical Reaction and Thermal Stratification Effects on Mixed Convection Heat and Mass Transfer along a Semi-Infinite Vertical PlateP. Geetha, M.B.K. MoorthyProblem statement: In this research the researchers studied and made an analysis to the heat and mass transfer characteristics in a viscous fluid over a semi-infinite vertical porous plate by taking into account the variable viscosity, chemical reaction and thermal stratification effects. Approach: The governing partial differential equations were transformed into a set of coupled non-linear ordinary differential equations, which … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 6,848 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsGermination Ecology of Rhanterium epapposum Oliv.Sameeha Zaman, Shyamala Padmesh, Harby TawfiqProblem statement: Rhanterium epapposum, locally called Arfaj is the national flower of Kuwait. The current situation of Rhanterium epapposum is quite critical in most areas of Kuwait. In fact it has completely disappeared from most parts of the country due to a combination of overgrazing, collecting for firewood and off road driving. Approach: Rhanterium epapposum is an excellent species for … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 7,618 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAdvective Heat Transport in an Unconfined Aquifer Induced by the Field Injection of an Open-Loop Groundwater Heat PumpStefano Lo Russo, Glenda TaddiaProblem statement: The increasing diffusion of low-enthalpy geothermal open-loop Groundwater Heat Pumps (GWHP) providing buildings air conditioning requires a careful assessment of the overall effects on groundwater system, especially in the urban areas. The impact on the groundwater temperature in the surrounding area of the re-injection well is directly linked to the aquifer properties. Physical processes affecting heat transport within … …American Journal of Environmental Sciences, Vol. 6, Issue 3 · 30 Jun 2010 · 7,970 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNumerical Comparison of Thermal Stratification due Natural Convection in Densified LOX, LN2 TanksSeyed Ali Jazayeri, Ehsan Molla Hasanzadeh KhoeiThe growth of natural circulation and thermal stratification inside LOX, LN2 storage tanks due to heat transfer from surroundings is investigated using a non-equilibrium, two-domain, mathematical model. The two-dimensional model is considered for the liquid domain in two cases and a lumped, thermodynamic model is utilized for vapor domain. The vapor is assumed to behave like an ideal gas. The … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 6,967 accessesView PDF Cite
