摘要
根据非矩形槽模型和非牛顿Ellis模型建立了非牛顿流体通过偏心环空的数学模型 ,并在极坐标下求出速度分布分析表达式 ,该方法适用范围广泛 ,并克服了以往数值差分解法的繁琐和误差。对于钻井泥浆的设计、化学物的注入有一定的实用价值。
According to non-rectangular cave model and Ellis model for non-Newton fluid flow,a mathematical model for non-Newton fluid flow in eccentric annular is developed.The velocity distribution analytical formula is given under polar coordination.This method has widely usage and overcomes the shortcoming of the numerical difference method.It is useful for the designing of drilling mud and chemical injection.
