摘要
为了对2种流态并存区域上井流问题的水头降深进行精确求解,在非线性渗流区域内对渗流规律中的非线性指数n进行了分区取值,对建立起来的水均衡方程,用Boltzmann变换进行求解,推导出了线性与非线性渗流区域内水头降深更精确的解析表达式。
In order to accurately solve the problem of water head drawdown of well flow with existence of two kinds of flow regime,the nonlinear exponent n of seepage process is decided for the nonlinear seepage sub-areas.The Boltzmann transformation is used to solve the water balance equation established.More accurate analytical formula is derived for the water head drawdown in the linear and nonlinear seepage areas.
