Research ArticleOpen accessEvery word in the titleDetermination of Kinetic Correction Coefficient of Fluid Flow Using a Generic Multiple Orifice Physical Scale Model StructureEmmanuel M. AdigioProblem statement: Diesel particulate filters are fast becoming integral parts of diesel engines, light and heavy duty, due to their potential in the reduction of particulate matter from exhaust gases and their noise muffling property. Consequently, several researchers are developing mathematical models for the study of fluid flow through the filter substrate and in the aiding of filter systems design. … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,553 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBoundary Effect on Marangoni Convection in a Variable Viscosity Fluid LayerN.Z. Abidin, N.M. Arifin, M.S.M. NooraniThe onset of Marangoni convection in a horizontal fluid layer with a free surface overlying a solid layer heated from below is studied. Problem is focused on the effect of the solid layer depth or its conductivity. The viscosity group, Rv, Biot number, Bi, depth ratio, dr and conductivity ratio, kr, are significant on determining the critical Marangoni number Mc … …Journal of Mathematics and Statistics, Vol. 4, Issue 1 · 31 Mar 2008 · 6,915 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFlow Characteristics in Elastic Arteries Using a Fluid-Structure Interaction ModelH. Niroomand Oscuii, M. Tafazzoli Shadpour, Farzan GhalichiIn this study the interaction of blood flow with arterial wall has been investigated using FSI (Fluid-Structure Interaction) modeling. Computer simulation of pulsatile blood flow was carried out on the basis of the time dependent axisymmetric Navier-Stokes equations for an incompressible Newtonian fluid flow. An elastic incompressible material with large deformation was considered for the arterial wall and momentum and … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 7,429 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSupercritical Fluid Extraction of Palm CarotenoidsPuah C. Wei, Choo Y. May, Ma A. Ngan, Chuah C. HockThe extraction of carotenoids from crude palm oil was carried out in a dynamic (flow- through) supercritical fluid extraction system. The carotenoids obtained were quantified using off-line UV-visible spectrophotometry. The effects of operating pressure and temperature, flow rate of the supercritical carbon dioxide (SC-CO2), sample size of feed used on the solubility of palm carotenoids were investigated. The results showed … …American Journal of Environmental Sciences, Vol. 1, Issue 4 · 31 Dec 2005 · 8,762 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePhysiologic Human Fluids and Swelling Behavior of Hydrophilic Biocompatible Hybrid Ceramo-Polymeric MaterialsAversa Raffaella, Relly Victoria V. Petrescu, Apicella Antonio, Florian Ion T. PetrescuAll synthetic and natural materials to be used in biomedical applications that involve the contact with human body need to be investigated for their physical and chemical modification induced by the human physiological fluids contact and sorption. The development and testing in human physiological equivalent fluids of new hybrid biomaterials are presented. The role of water and its equilibrium modification … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 8 Nov 2016 · 8,387 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Evaporator Section Lengths and Working Fluids on Operational Limit of Closed Loop Oscillating Heat Pipes with Check Valves (CLOHP/CV)P. Meena, S. Rittidech, P. TammasaengThis research aims to the effect of evaporator section lengths and working fluids on operational limit of closed loop oscillating heat pipes with check valves (CLOHP/CV) with R123 Ethanol and Water were used as the working fluids. A set of CLOHP/CV was made of copper tubes in combination of following dimension: 1.77 mm inside diameter: 10 turns: 5, 10 and … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,776 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNa,K-ATPase α Subunit-like Immunoreactive Proteins in Human Body FluidsJeng-Hsiung F. PengNa,K-ATPase was recently considered a target for breast cancer treatment since its potent inhibitors ouabain and related digitalis compounds that were reported circulating in body fluids before, were found to possess potent anti-breast cancer activity. Based on this finding, it is hypothesized that Na,K-ATPase derivatives could be circulating in the body and potential candidate biomarkers for early disease detection. Western … …American Journal of Immunology, Vol. 2, Issue 1 · 31 Mar 2006 · 6,892 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePreparation of Magnetorheological Fluids Using Different Carriers and Detailed Study on Their PropertiesVikram G. Kamble, Shreedhar Kolekar, Chetan MadivalarHigh sensitive and intelligence are the main function of the Magneto Rheological Fluids (MRF). In this research work, magneto rheological samples are prepared with two different carrier oils (Honge and Castor) independently. Both the samples are mixed and prepared with same concentration of iron particles. In order to reduce the sedimentation fine lithium grease is added as stabilizer for both … …Current Research in Nanotechnology, Vol. 6, Issue 1 · 4 Sep 2015 · 13,120 accessesView PDFCite
