| 1 | 3-D NUMERICAL SIMULATION OF CONVOY-GENERATED WAVES IN A RESTRICTED WATERWAY显示文摘We consider waves generated by the passing of convoys in a restricted waterway. The magnitude of these waves depends mainly on the geometrical and kinematical parameters of the convoy, such as the speed and the hull geometry. The objective of this study is to predict the relationship between these geometrical and kinematical parameters and the amplitude of ship-generated waves as well as the water plane drawdown. Numerical simulations are conducted by solving the 3-D Navier-Stokes equations along with the standard k model for turbulent processes. The results are compared first with the empirical model and second with experimental measurements performed by the French company Compagnie National du Rh ne (CNR). | OUAHSINE Abdellatif SMAOUI Hassan SERGENT Philippe | 2012 | Journal of Hydrodynamics2012，24，3： | 9 |
| 2 | Contribution of the FPGAs for Complex Control Algorithms: Sensorless DTFC with an EKF of an Induction Motor显示文摘In a conventional direct torque control(CDTC) of the induction motor drive, the electromagnetic torque and the stator flux are characterized by high ripples. In order to reduce the undesired ripples, several methods are used in the literature. Nevertheless,these methods increase the algorithm complexity and dependency on the machine parameters such as the space vector modulation(SVM). The fuzzy logic control method is utilized in this work to decrease these ripples. Moreover, to eliminate the mechanical sensor the extended kalman filter(EKF) is used, in order to reduce the cost of the system and the rate of maintenance. Furthermore, in the domain of controlling the real-time induction motor drives, two principal digital devices are used such as the hardware(FPGA) and the digital signal processing(DSP). The latter is a software solution featured by a sequential processing that increases the execution time. However, the FPGA is featured by a high processing speed because of its parallel processing. Therefore, using the FPGA it is possible to implement complex algorithms with low execution time and to enhance the control bandwidth. The large bandwidth is the key issue to increase the system performances. This paper presents the interest of utilizing the FPGAs to implement complex control algorithms of electrical systems in real time. The suggested sensorless direct torque control using the fuzzy logic(DTFC) of an induction motor is successfully designed and implemented on an FPGA Virtex 5 using xilinx system generator. The simulation and implementation results show proposed approach s performances in terms of ripples, stator current harmonic waves, execution time, and short design time. | Saber Krim Soufien Gdaim Abdellatif Mtibaa Mohamed Faouzi Mimouni | 2019 | International Journal of Automation and computing2019，16，2： | 3 |
| 3 | 生料易烧性指数K1450的计算和影响因素研究与应用实践显示文摘生料易烧性指数K_(1450)是一个与C_3S形成化学反应速度常数成正比的技术参数,可根据配入煤灰掺入量后的生料化学成分及1 450℃煅烧样品的f-CaO含量进行计算。K_(1450)值越高,表明生料易烧性越好;其显著性影响因素包括生料中粗颗粒石英含量、氟离子含量、熟料设计的液相量和铝率。根据K_(1450)数值高低,可以比较准确地预测水泥窑熟料煅烧热耗的相对变化;当K_(1450)从30提高至70,熟料煅烧热耗可降低10%以上。易烧性较好的生料(K_(1450)>70),由于可在更快的升温速率和更短的高温带通过时间下实现熟料烧成,且可显著减轻窑内还原气氛,因此熟料煅烧热耗较低;若通过进一步优化,使熟料中的A矿能够获得合理的晶体大小及矿物形貌,可显著提高熟料的活性。 | 郭随华 任兵建 姚燕 Abdellatif Boumiz | 2018 | 水泥2018，0，10： | 3 |
| 4 | Assessment of ship manoeuvrability by using a coupling between a nonlinear transient manoeuvring model and mathematical programming techniques显示文摘In this paper,a numerical method based on a coupling between a mathematical model of nonlinear transient ship manoeuvring motion in the horizontal plane and Mathematical Programming(MP)techniques is proposed.The aim of the proposed procedure is an efficient estimation of optimal ship hydrodynamic parameters in a dynamic model at the early design stage.The proposed procedure has been validated through turning circle and zigzag manoeuvres based on experimental data of sea trials of the 190 000-dwt oil tanker.Comparisons between experimental and computed data show a good agreement of overall tendency in manoeuvring trajectories. | TRAN KHANH Toan OUAHSINE Abdellatif NACEUR Hakim EL WASSIFI Karima | 2013 | Journal of Hydrodynamics2013，25，5： | 3 |
| 5 | Fenton treatment of olive oil mill wastewater—applicability of the method and parameters effects on the degradation process显示文摘The low biodegradability of polyphenolic compounds typically found in olive processing indicated that biological treatment is not always successful in the treatment of olive oil mill wastewater in term of COD removal. In this study the results of investigations on the applicability of Fenton’s reagent in the treatment of this effluent were discussed. The efficiency of this method was determined. 86 % of removal COD was obtained using 5 mol H 2O 2 and 0.4 mol Fe 2+ per liter of crude OMW. The main parameters that govern the complex reactive system, i.e., time, pH, [H 2O 2] and [Fe(II)] were studied. | Bensalah Nasr Bedoui Ahmed Gadri Abdellatif | 2004 | Journal of Environmental Sciences2004，16，6： | 2 |

| 10 | Impacts of ship movement on the sediment transport in shipping channel显示文摘The duration of ship-generated waves(wake waves) and accelerated currents can generate significant influences on the sediment transport. A 3-D numerical model is presented to estimate these effects. The hydrodynamic model is the 3-D Reynolds averaged Navier-Stokes(RANS) equations including the standard k-ε model while the 3-D convection-diffusion model is for the resuspended sediment transport. This hydro-sedimentary model is firstly validated with the trench experimental results, and then applied to the open channel with a moving ship. The computed results demonstrate that the resuspension generation mainly depends on ship speeds, barge number, and the relative distance away from ship. The acceleration effects of ship on the sediment transport are analyzed as well. | JI Sheng-cheng OUAHSINE Abdellatif SMAOUI Hassan SERGENT Philippe JING Guo-qing | 2014 | Journal of Hydrodynamics2014，26，5： | 1 |
