对分别浸入3种纳米流体(ZnO-水,SiO2-水,TiO2-水)的平板近壁面流动的湍流边界层的对数规律进行数值分析.采用CFD程序对边界层和流体动力流动进行数值模拟.使用已发表的测量点对数值模型进行验证,结果表明一致性较好.对流速0.04 m/s,0.4 m/s,4 m/s以及纳米颗粒浓度0.1％和5％的情况进行模拟.研究了纳米颗粒浓度对速度、温度分布、壁面剪切应力和湍流强度的影响.结果表明:沿势流层的黏性亚层、缓冲层和对数律层可以基于具有单壁距离区域的弯曲质量进行分析.可见,与其他区域相比,黏性亚层面积最大.另一方面,温度变化与热边界层厚度有关的区域在流速减小时也减小,热边界层离前缘越来越深,而纳米颗粒体积分数的增加对壁面剪切应力的影响较小.在所有情况下,边界层的厚度都随着流速的增加而减小,而纳米颗粒浓度的增加会使边界层的厚度增加.更准确地说,对数层在Y+=50和Y+=95之间最小.在所研究的纳米流体中,φ=5％时的边界层温度高于φ=0.1％时的边界层温度.而Y+=1时,结果正好相反,φ=0.1％时的温度比φ=5％的更高.当流速分别为v=4,0.4,0.04 m/s时,湍流强度峰值分别出现在Y+=100,Y+=10和Y+=8时.“,”A numerical analysis of the log-law behavior for the turbulent boundary layer of a wall-bounded flow is performed over a flat plate immersed in three nanofluids (ZnO-water, SiO2-water, TiO2-water). Numerical simulations using CFD code are employed to investigate the boundary layer and the hydrodynamic flow. To validate the current numerical model, measurement points from published works were used, and the compared results were in good compliance. Simulations were carried out for the velocity series of 0.04, 0.4 and 4 m/s and nanoparticle concentrations 0.1％ and 5％. The influence of nanoparticles \' concentration on velocity, temperature profiles, wall shear stress, and turbulent intensity was investigated. The obtained results showed that the viscous sub-layer, the buffer layer, and the log-law layer along the potential-flow layer could be analyzed based on their curving quality in the regions which have just a single wall distance. It was seen that the viscous sub-layer is the biggest area in comparison with other areas. Alternatively, the section where the temperature changes considerably correspond to the thermal boundary layer\'s thickness goes a downward trend when the velocity decreases. The thermal boundary layer gets deep away from the leading edge. However, a rise in the volume fraction of nanoparticles indicated a minor impact on the shear stress developed in the wall. In all cases, the thickness of the boundary layer undergoes a downward trend as the velocity increases, whereas increasing the nanoparticle concentrations would enhance the thickness. More precisely, the log layer is closed with log law, and it is minimal between Y+=50 and Y+=95. The temperature for nanoparticle concentrationφ=5％is higher than that forφ=0.1％, in boundary layers, for all studied nanofluids. However, it is established that the behavior is inverted from the value of Y+=1 and the temperature for φ=0.1％ is more important than the case of φ=5％. For turbulence intensity peak, this peak exists at Y+=100 for v=4 m/s, Y+=10 for v=0.4 m/s and Y+=8 for v=0.04 m/s.
