摘要

考虑了在MHD、氧化铝纳米流体流、热辐射和霍尔电流存在的情况下,对流发热和板的振荡运动的影响。该板在温度均匀的情况下沿其轴线和谐振荡。必须将量纲方程转换为具有一组无量纲参数的无量纲方程。利用拉普拉斯变换技术得到精确的解。用普朗特数(Pr)、格拉绍夫数(Gr)、霍尔参数(m)、磁参数(m)、辐射(R)、固体体积分数等参数分析了速度和温度的性质(ᵠ), 相位角(ω)。通过图形讨论了一次速度和二次速度的影响。观察到,霍尔参数(m)的增加降低了一次速度,Grashof数的增加导致两种速度的增加,并且固体体积分数的增加提高了温度。努塞尔数和表面摩擦系数值已在表中表示。很明显,辐射的增加增加了努塞尔数的值,并且相位角值的增加也减少了皮肤摩擦系数值。

Numerical investigation of heat transfer & hall effects on MHD nanofluid flow past over an oscillating plate with radiation
The effects of convective heat generation and the oscillatory motion of a plate in the presence of MHD, Alumina nanofluid flow, thermal radiation, and Hall current are considered. The plate oscillates harmonically in its axes with uniform temperature. The dimensional equations have to be changed into non-dimensional equations with a set of dimensionless parameters. The Laplace transformation technique is utilized to get an exact solution. The possessions of velocity and temperature are analyzed with several parameters like Prandtl number (Pr), Grashof number (Gr), Hall parameter (m), magnetic parameter (M), radiation (R), solid volume fraction(ᵠ), phase angle(ω).The influence of primary and secondary velocity is discussed by the graph. It is observed that the increment of Hall parameter (m) diminishes the primary velocity, an increment of Grashof number leads to an increase in both velocities, and increasing solid volume fraction raises the temperature. The Nusselt number and skin friction coefficient values have expressed in the table. It is apparent that an increment of radiation increased the value of the Nusselt number and also an increment of phase angle value diminished the skin friction coefficient value.

期刊介绍: Journal of Thermal Enginering is aimed at giving a recognized platform to students, researchers, research scholars, teachers, authors and other professionals in the field of research in Thermal Engineering subjects, to publish their original and current research work to a wide, international audience. In order to achieve this goal, we will have applied for SCI-Expanded Index in 2021 after having an Impact Factor in 2020. The aim of the journal, published on behalf of Yildiz Technical University in Istanbul-Turkey, is to not only include actual, original and applied studies prepared on the sciences of heat transfer and thermodynamics, and contribute to the literature of engineering sciences on the national and international areas but also help the development of Mechanical Engineering. Engineers and academicians from disciplines of Power Plant Engineering, Energy Engineering, Building Services Engineering, HVAC Engineering, Solar Engineering, Wind Engineering, Nanoengineering, surface engineering, thin film technologies, and Computer Aided Engineering will be expected to benefit from this journal’s outputs.
