摘要
根据 N-S 方程和层流条件推导了椭圆管内的流体运动方程,并根据边界条件,得出了椭圆管内层流时的流速分布规律及流量-压力降方程,供研究参考.
According to N-S equation and laminar condition,the fulid movement equation inside the ovel tube is derived,then according to boundary term,it get a requlation of velocity for oval tube inside laminar and dis- charge-pressures decline equation for ones that study reference.
