| 1 | Comparative analysis of different static mixers performance by CFD technique:An innovative mixer显示文摘The flow and mixing behavior of two miscible liquids has been studied in an innovative static mixer by using CFD,with Reynolds numbers ranging from 20 to 160.The performance of the new mixer is compared with those of Kenics,SMX,and Komax static mixers.The pressure drop ratio(Z-factor),coefficient of variation(CoV),and extensional efficiency(α)features have been used to evaluate power consumption,distributive mixing,and dispersive mixing performances,respectively,in all mixers.The model is firstly validated based on experimental data measured for the pressure drop ratio and the coefficient of variation.CFD results are consistent with measured data and those obtained by available correlations in the literature.The new mixer shows a superior mixing performance compared to the other mixers. | M.M.Haddadi S.H.Hosseini D.Rashtchian Martin Olazar | 2020 | Chinese Journal of Chemical Engineering2020，28，3： | 9 |

| 3 | A novel control strategy for load converter of DC isolated distribution system under unbalanced loading conditions显示文摘A novel control strategy for the load converter supplying the unbalanced AC load in a DC isolated distribution system is presented. The control algorithm results in balanced and sinusoidal load voltages under unbalanced AC loading. The unbalanced load is characterized in the d-q-0 rotating coordinate based on symmetrical sequence components. Also, the mathematical model of the load converter in both a-b-c and d-q-0 coordinates is derived by using the average large signal model. Then, two control strategies for the load converter are presented. The first one uses the conventional d-q-0 controller to ensure the voltage and current regulation. The second one is a newly proposed control strategy based on the decomposition of the voltage and current into in-stantaneous positive, negative, and zero sequences. These three sequences are controlled independently in their own reference frames as DC signals. The performance of the load converter using these two control strategies is compared. Simulation results show the validity and capability of the newly proposed control strategy. | R.NOROOZIAN M.ABEDI G.B.GHAREHPETIAN S.H.HOSSEINI | 2009 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2009，10，6： | 1 |
| 4 | Smart computing approach for design and scale-up of conical spouted beds with open-sided draft tubes显示文摘Open-sided draft tubes provide an optimal gas distribution through a cross flow pattern between the spout and the annulus in conical spouted beds.The design,optimization,control,and scale-up of the spouted beds require precise information on operating and peak pressure drops.In this study,a multi-layer perceptron(MLP)neural network was employed for accurate prediction of these hydrodynamic characteristics.A relatively huge number of experiments were accomplished and the most influential dimensionless groups were extracted using the Buckingham-pi theorem.Then,the dimensionless groups were used for developing the MLP model for simultaneous estimation of operating and peak pressure drops.The iterative constructive technique confirmed that 4-14-2 is the best structure for the MLP model in terms of absolute average relative deviation(AARD%),mean square error(MSE),and regression coefficient(R^(2)).The developed MLP approach has an excellent capacity to predict the transformed operating(MSE=0.00039,AARD%=1.30,and R^(2)=0.76099)and peak(MSE=0.22933,AARD%=11.88,and R2=0.89867)pressure drops. | M.Karimia B.Vaferi S.H.Hosseini M.Olazar S.Rashidi | 2021 | Particuology2021，19，2： | 1 |
| 5 | Effect of Gaussian size distribution width on minimum fluidization velocity in tapered gas–solid fluidized beds显示文摘This paper investigated the effect of Gaussian distribution width,average particle diameter,particle loading,and the tapered angle on minimum fluidization velocity(U_(mf))by conducting extensive experiments in tapered fluidized beds.Three powders with Gaussian size distribution and different distribution widths were used in the experiments.An increase in U_(mf)with increasing the average particle diameter,particle loading,and the tapered angle was observed.There was also a nonmonotonic behavior of Umf as the Gaussian distribution width increased.An empirical correlation including dimensionless groups for predicting Umf in tapered beds was developed in which the effect of distribution width was considered.The proposed correlation predictions were in good agreement with the experimental data,with a maximum deviation of 16.5%and average and standard deviations of,respectively,6.4%and 7.4%.The proposed correlation was also compared with three earlier models,and their accuracy was discussed. | Mojtaba Rasteh Goodarz Ahmadi S.H.Hosseini | 2022 | Particuology2022，20，7： | 0 |
| 6 | 工艺参数对摩擦辅助管应变法加工管组织和力学性能的影响显示文摘研究了摩擦辅助管应变(FATS)法对管材组织和力学性能的影响。采用有限元法分析并进行实验测试。用Taguchi设计(ATD)进行分析,改变转速、进给速率和模具角度来进行数值和实验试验。结果表明,提高进给速率和降低转速提高了Zener-Hollomon参数(Z),减小了平均晶粒尺寸,而对模具角度没有显著影响。增加Z值可以减小晶粒尺寸,增强加工样品的流动应力。实验结果表明,具有最大Z值的样品其晶粒尺寸从初始的40μm细化到8μm,其流动应力增加5倍。 | S.H.HOSSEINI M.SEDIGHI | 2021 | Journal of Central South University2021，28，10： | 0 |
| 7 | 采用上限方法确定反挤压加工功和最优坯料半径(英文)显示文摘采用上限方法开发了一种新的改进反挤压方法。在这个方法中,将变形区划分为4个不同的区域,然后对每个区的运动许可速度场进行了设定。对变形区的总耗散功和挤压功进行了计算。对一些重要的几何参数与挤压力和耗散功的关系进行了探讨。考虑到最小的相对挤压压力,通过上限方法获得了最优的坯料半径。同时,采用有限元法对问题进行了分析并与采用上限方法获得的结果进行了比较。最后,将上限方法和有限元方法的计算结果与工业纯铝的实验结果进行了比较,结果表明他们之间吻合较好。 | S.H.HOSSEINI K.ABRINIA | 2016 | Transactions of Nonferrous Metals Society of China2016，26，8： | 0 |
