| 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 | Cellulose-based composite scaffolds for bone tissue engineering and localized drug delivery显示文摘Natural bone constitutes a complex and organized structure of organic and inorganic components with limited ability to regenerate and restore injured tissues,especially in large bone defects.To improve the reconstruction of the damaged bones,tissue engineering has been introduced as a promising alternative approach to the conventional therapeutic methods including surgical interventions using allograft and autograft implants.Bioengineered composite scaffolds consisting of multifunctional biomaterials in combination with the cells and bioactive therapeutic agents have great promise for bone repair and regeneration.Cellulose and its derivatives are renewable and biodegradable natural polymers that have shown promising potential in bone tissue engineering applications.Cellulose-based scaffolds possess numerous advantages attributed to their excellent properties of non-toxicity,biocompatibility,biodegradability,availability through renewable resources,and the low cost of preparation and processing.Furthermore,cellulose and its derivatives have been extensively used for delivering growth factors and antibiotics directly to the site of the impaired bone tissue to promote tissue repair.This review focuses on the various classifications of cellulose-based composite scaffolds utilized in localized bone drug delivery systems and bone regeneration,including cellulose-organic composites,cellulose-inorganic composites,cellulose-organic/inorganic composites.We will also highlight the physicochemical,mechanical,and biological properties of the different cellulose-based scaffolds for bone tissue engineering applications. | Mahsa Janmohammadi Zahra Nazemi Amin Orash Mahmoud Salehi Amir Seyfoori Johnson V.John Mohammad Sadegh Nourbakhsh Mohsen Akbari | 2023 | Bioactive Materials2023，，2： | 3 |
| 3 | A high performance gas–liquid two-phase flow meter based on gamma-ray attenuation and scattering显示文摘The ability to precisely estimate the void fraction of multiphase flow in a pipe is very important in the petroleum industry. In this paper, an approach based on our previous works is proposed for predicting the void fraction independent of flow regime and liquid phase density changes in gas–liquid two-phase flows. Implemented technique is a combination of dual modality densitometry and multi-beam gamma-ray attenuation techniques. The detection system is comprised of a single energy fan beam,two transmission detectors, and one scattering detector. In this work, artificial neural network(ANN) was also implemented to predict the void fraction percentage independent of the flow regime and liquid phase density changes. Registered counts in three detectors and void fraction percentage were utilized as the inputs and output of ANN, respectively. By applying the proposed methodology, the void fraction was estimated with a mean relative error of less than just 1.2480%. | G. H. Roshani E.
