摘要
首先推导了具有较高精度的、新的宾汉液体结构流解析解。在此基础上,应用广义稳定性参数Z,研究了同心环空中宾汉液体轴向层流、结构流的稳定性;提出了判别流动状态的计算方法;分析了影响流动稳定性的因素。文未用SPE11993中的实验资料对本文理论作了验证,得到了理论符合实际的结论。
We deduced a new and accurate analytic solution of the structure flow of Bingham
fluids. On the basis of the result and using the generalizing stability parameter Z, we
studied the axial laminar and structural flow of Bingham fluids in concentric annuli, and
proposed the calculating methods to distinguish the flow characterization, and mean-
while, analyzed the influence factors on the flow stability. The results of theoretical
analyses are in good correspondence with the findings in published papers.
