| 1 | Experimental study of ice accretion effects on aerodynamic performance of an NACA 23012 airfoil显示文摘In this paper,the effects of icing on an NACA 23012 airfoil have been studied.Experiments were applied on the clean airfoil,runback ice,horn ice,and spanwise ridge ice at a Reynolds number of 0.6 106 over angles of attack from 8° to 20°,and then results are compared.Generally,it is found that ice accretion on the airfoil can contribute to formation of a flow separation bubble on the upper surface downstream from the leading edge.In addition,it is made clear that spanwise ridge ice provides the greatest negative effect on the aerodynamic performance of the airfoil.In this case,the stall angle drops about 10° and the maximum lift coefficient reduces about50% which is hazardous for an airplane.While horn ice leads to a stall angle drop of about 4° and a maximum lift coefficient reduction to 21%,runback ice has the least effect on the flow pattern around the airfoil and the aerodynamic coefficients so as the stall angle decreases 2° and the maximum lift reduces about 8%. | Sohrab Gholamhosein Pouryoussefi Masoud Mirzaei Mohammad-Mahdi Nazemi Mojtaba Fouladi Alireza Doostmahmoudi | 2016 | Chinese Journal of Aeronautics2016，29，3： | 12 |
| 2 | A comprehensive experimental evaluation of asphaltene dispersants for injection under reservoir conditions显示文摘As the efficiency of dispersants with different origins is questionable for each typical oil sample,the present study provides a reproducible and reliable method for screening asphaltene dispersants for a typical asphaltenic crude oil.Four different asphaltene dispersants(polyisobutylene succinimide.polyisobutylene succinic ester,nonylphenol-formaldehyde resin modified by polyamines.and rapeseed oil amide) were prepared and their performance on two oils from an Iranian field under laboratory and reservoir conditions was studied.A thorough analysis including ash content and SARA tests was performed on the solid asphaltene particles to characterize the nature of deposits.Then a highly efficient carrier fluid,which is crucial when injecting dispersant into the wells,was selected from a variety of chemicals by comparing their solubility.In the next step,using an optical microscope,a viscometer,and a Turbiscan.the screening of dispersants under laboratory conditions was done on a mixture of dead oil and dispersant to evaluate the onset of asphaltene precipitation and its stability when titrating by a precipitant.Finally,two different mixtures of the efficient dispersants.live oil,and carrier fluid were used with the solid detection system(SDS) and the filtration method to examine their effects on the onset pressure of asphaltene precipitation and the asphaltene content of the crude oil under reservoir conditions.The results show that the combination of experimental methods used in this work could be consistently applied to screening asphaltene dispersants.Among the four different dispersants applied here,the dispersant based on nonylphenol-formaldehyde resin modified by polyamines showed the best performance on the available live oils.This chemical modified the onset pressure of asphaltene precipitation of light oil from 4300 psi to about 3600 psi and decreased the precipitated asphaltene of heavy oil by about 30%. | Hamed Firoozinia Kazem Fouladi Hossein Abad Akbar Varamesh | 2016 | Petroleum Science2016，13，2： | 6 |
