| 1 | Numerical and experimental study of Boussinesq wall horizontal turbulent jet of fresh water in a static homogeneous environment of salt water显示文摘This paper investigates a numerical and experimental study about buoyant wall turbulent jet in a static homogeneous environment. A light fluid of fresh water is injected horizontally and tangentially to a plane wall into homogenous salt water ambient. This later is given with different values of salinity and the initial fractional density is small, so the applicability of the Boussinesq approximation is valid. Since the domain temperature is assumed to be constant, the density of the mixture is a function of the salt concentration only. Mathematical model is based on the finite volume method and reports on an application of standard k- ? turbulence model for steady flow with densimetric Froude numbers of 1-75 and Reynolds numbers of 2 000-6 000. The basic features of the model are the conservation of mass, momentum and concentration. The boundaries of jet body, the radius and cling length are determined. It is found that the jet spreading and behavior depend on the ratio between initial buoyancy flux and momentum, i.e., initial Froude number, and on the influence of wall boundary which corresponds to Coanda effect. Laboratory experiments were conducted with photographic observations of jet trajectories and numerical results are described and compared with the experiments. A good agreement with numerical and experimental results has been achieved. | BELCAID Aicha LE PALEC Georges DRAOUI Abdeslam | 2015 | Journal of Hydrodynamics2015，27，4： | 2 |
| 2 | Rh/ZnO-Al_2O_3催化剂用于巴豆醛选择性加氢(英文)显示文摘Gas phase hydrogenation of crotonaldehyde was performed over 1 wt% Rh/ZnO-Al2O3 catalysts with various Zn/Rh atomic ratios. Monometallic Rh/Al2O3 was also prepared for comparison. The samples were prepared by the successive impregnation of Al2O3 with chlo-ride precursors of zinc and rhodium. The solids have been characterized by H2 chemisorption,temperature-programmed reduction,scanning electron microscopy,and cyclohexane dehydrogenation. Their catalytic behaviour in the gas phase crotonaldehyde hydrogenation reaction after reduction treatment in flowing hydrogen at 723 K was investigated. The relationship between catalytic activity,selectivity for crotyl alcohol,and physicochemical properties of the catalysts was examined. Results obtained showed that the presence of Zn clearly promotes the hydrogenation of the carbonyl bond. The catalyst with Zn/Rh atomic ratio of 5 displayed good catalytic stability and the highest selectivity for crotyl alcohol(70%) along with alloy formation. | Mouna AOUN Aicha BENAMAR Mohamed CHATER | 2011 | 催化学报2011，32，7： | 2 |

| 4 | Hidden attractors in a new fractional-order discrete system: Chaos, complexity, entropy, and control显示文摘This paper studies the dynamics of a new fractional-order discrete system based on the Caputo-like difference operator.This is the first study to explore a three-dimensional fractional-order discrete chaotic system without equilibrium.Through phase portrait,bifurcation diagrams,and largest Lyapunov exponents,it is shown that the proposed fractional-order discrete system exhibits a range of different dynamical behaviors.Also,different tests are used to confirm the existence of chaos,such as 0-1 test and C0 complexity.In addition,the quantification of the level of chaos in the new fractional-order discrete system is measured by the approximate entropy technique.Furthermore,based on the fractional linearization method,a one-dimensional controller to stabilize the new system is proposed.Numerical results are presented to validate the findings of the paper. | Adel Ouannas Amina Aicha Khennaoui Shaher Momani Viet-Thanh Pham Reyad El-Khazali | 2020 | Chinese Physics B2020，29，5： | 2 |

| 8 | Deposition of Phosphate Nanoparticles onto Textile Fabrics via Sol-gel Method and Their Kinetics Desorption Studies显示文摘In this paper,phosphate nanoparticles were coated on cotton(CO)and polyester(PES)textile surfaces by sol-gel method using tetraethylorthosilicate(TEOS)and chloropropyltriethoxysilane(CPTS)as silica precursors.The deposited nanoparticles were observed with scanning electronic microscopy energv-dispersive X-ray spectroscopy(SEM-EDX).The release kinetics of phosphorus(P)from these textiles into the aqueous medium(Aq),acid(Ac),and basic(Ba)artificial sweats were then studied.The released amount of phosphorus was evaluated by the inductively coupled plasma(ICP)according to ISO NF EN 16711-2 procedure.The results revealed that the release of P into the aqueous medium is lower than in the artificial sweat.The kinetics data[the phosphoras desorption amount(mg/g)as a iunction of time]were modeled according to five models:the first order,the second order,the third order,simple Elovich and parabolic diffusion.The suitable model was chosen based on the coefficient of determination(R2)and the calculation of the sum of the absolute errors(EABS),which describes the error between the theoretical and experimental values.SEM observations were also carried out on the fabrics after desorption in order to show the impact of desorption on their morphology.Furthermore,the impact of P release on the tensile strength of CO and PES fabrics was investigated using a uniaxial tensile test.The thennal stability of all samples before and after desorption was assessed by thermogravimetric aiialysis(ATG). | Mohamed El MESSOUDI Aicha BOUKHRISS Laila SADALLAH Laila SAJID M'hamed El KOUALI Said GMOUH | 2020 | Chemical Research in Chinese Universities2020，36，5： | 1 |
