论文摘要
理论上研究了由恒压梯度引起的管道中的carreau-yasuda流体的稳定poiseuille流动。事实证明,在粘度模型参数的某些值下,问题具有经典的解决方案,而在其他方面则具有广义解决方案。对于后者,发现了必要且充分的条件,这取决于压力梯度和Carreau-Yasuda模型参数。
The steady Poiseuille flow of Carreau-Yasuda fluid in a pipe, caused by constant pressure gradient, is studied theoretically. It is proved that at some values of the viscosity model parameters, the problem has a classical solution, while at others - generalized solution. For the latter, a necessary and sufficient condition is found, which depends on the pressure gradient and Carreau-Yasuda model parameters.
