摘要:
对Prandtl边界层方程进行了分析,探讨了它的不足之处; 提出了(p)/(y)=μ(2v)/(y2)22的新假设,并对过渡区方程进行了假设,同时提出了适合绕平板流动及传热全过程的控制方程.文中采用数值分析方法,用控制方程对绕光滑平板流动及传热加以研究,计算结果表明,本文的控制方程解相对于Prandtl边界层方程,与实验更为接近,从而验证了本文假设的合理性.
Abstract:
This paper analyzes the shortcoming of Prandtl boundary layer equation, presents a new hypothesis of pressure gradient in y direction and transition area equation, and also presents a control equation suited for the flow and heat transfer over flat plate. The computation of boundary layer control equation on the flow and heat transfer past flat plate are conducted by using numerical method. The results show the approach made by control equation is more applicable than that of Prandtl layer, and demonstrate the reasonability of the new hypothesis presented by this paper.
