摘要
本文用匹配渐近展开法导出二维翼型在非惯性坐标系中的一阶和二阶边界层方程,消去压强项后,一阶边界层方程与经典边界层方稃相同;惯性力的作用在二阶边界层中才出现。
The first-order and second-order boundary layer equations in noninertial reference frame is derived using the technique of matched asymptotic expansion. The first-order boundary layer equation is identical to the classical boundary layer equation as the pressure term is eliminated; the noninertial effect is of second-order.
