Nalini S Patil, Vishwambhar S. Patil, J. N. Salunke

摘要:

分析了在横向均匀磁场存在下,粘性不可压缩导电纳米流体在考虑抽吸或注入的拉伸薄板上的稳态流动和化学反应.本模型的实验证明,揭示热泳和布朗运动的影响。研究了控制方程的相似解,并采用四阶龙格-库塔积分格式和打靶技术进行了数值求解。绘制了相关参数对速度分布、浓度分布和温度分布的影响曲线。讨论了局部摩阻系数、约化Nusselt数和约化Sherwood数等参数对计算结果的影响。实验装置显示与文献的结果吻合良好。

英文摘要:

An analysis is carried out to examine the effects of the steady flow of an electrically conducting viscous incompressible nanofluid in the existence of a uniform transverse magnetic field with chemical reaction over a stretching sheet considering suction or injection. The present model is demonstrated experimentally to reveal the effects of Thermophoresis and Brownian motion. Similarity solutions are investigated for the governing equations and solved numerically by using a shooting technique with fourth-order Runge-Kutta integration scheme. The impact of associated parameters on velocity profile, concentration profile and temperature profile is plotted graphically. Also the impact of local skin friction coefficient, the reduced Nusselt number and the reduced Sherwood number are discussed. The experimental setup revealed good agreement of the results with the literature.
