| 1 | 霍尔效应和欧姆热效应下纳米流体通过弯曲通道时的蠕动(英文)显示文摘纳米流体以其优异的热物理性质吸引了许多科学家。在常规流体中加入少量的纳米粒子会显著地增强传热特性。纳米材料的可持续性和效率对纳米技术的进步具有关键作用。本文分析了霍尔效应、欧姆热效应和速度滑移对纳米流体蠕动的影响。考虑了对流边界条件和热的产生/吸收,以促进传热特性。在曲线坐标下导出了弯曲通道中蠕动的控制方程。在长波长和小雷诺数的假设条件下,对方程进行了数值求解。研究表明,纳米流体提高了传热速率,降低了流体温度。Hartman数和Hall参数在流体运动和传热特性上表现出相反的行为。在存在速度滑移的情况下,压力梯度迅速减小,在通道的狭小区域表现出主导作用。 | T.HAYAT B.AHMED F.M.ABBASI A.ALSAEDI | 2019 | Journal of Central South University2019，26，9： | 2 |
| 2 | Numerical Study of Mixed Convective Peristaltic Flow through Vertical Tube with Heat Generation for Moderate Reynolds and Wave Numbers显示文摘The current study focuses on the numerical investigation of the mixed convective peristaltic mechanism through a vertical tube for non-zero Reynolds and wave number. In the set of constitutional equations, energy equation contains the term representing heat generation parameter. The problem is formulated by dropping the assumption of lubrication theory that turns the model mathematically into a system of the nonlinear partial differential equations. The results of the long wavelength in a creeping flow are deduced from the present analysis. Thus, the current study explores the neglected features of peristaltic heat flow in the mixed convective model by considering moderate values of Reynolds and wave numbers. The finite element based on Galerkin's weighted residual scheme is applied to solve the governing equations. The computed solution is presented in the form of contours of streamlines and isothermal lines, velocity and temperature profiles for variation of different involved parameters. The investigation shows that the strength of circulation for stream function increases by increasing the wave number and Reynolds number. Symmetric isotherms are reported for small values of time-mean flow. Linear behavior of pressure is noticed by vanishing inertial forces while the increase in pressure is observed by amplifying the Reynolds number. | Tariq Javed B.Ahmed M.Sajid | 2018 | Communications in Theoretical Physics2018，69，4： | 0 |
| 3 | 半刚性钢框架结构的侧移(第一部分:规则框架)显示文摘水平侧移是半刚性框架结构设计中最关键的控制因素,因为此类框架布置中不带有支撑。该文研究了规则半刚性钢框架的侧移性能,也就是假定所有梁和柱的布置方式都相同,以此得出一些设计图表用来直接确定框架侧移,这样可以减少数值分析的工作。Schueller方程除了包含框架结构本身的刚度之外,还考虑了修正后的结点刚度。所有提出的方法都已经过数值分析算例的验证。 | M.Ashraf D.A.Nethroct B.Ahmed | 2005 | 建筑钢结构进展2005，7，1： | 0 |
