对拐角附近的幂律流体流动进行了局部分析。流函数的方程在平面极坐标中允许分离的解。证明了径向行为是代数的,并给出了不同转角指数和幂指数时的结果。此外,还得到了涡旋结构发生的临界角是幂指数的函数。
A local analysis of the flow of power law fluids near corners is performed. The equation for the stream function is shown to allow separated solutions in plane polar coordinates. The radial behavior is shown to be algebraic and results are given for the exponent for different values of corner angle and power law exponent. In addition, the critical angle for the onset of an eddy structure is found as function of the power law exponent.
