提出了用电模拟法求解边界层方程的计算步骤。以沿半无限平板和水平圆管进口区中层流速度分布计算为例,证明了计算方法是正确的。这种解法在边界条件复杂、物理性质可变、温度梯度巨大……等情况时特别有用。 A calculation method of solving the boundary layer equation by electric simulation is proposed. Taking the calculation of the laminar velocity distribution along the semi-infinite plate and the horizontal pipe inlet as an example, the calculation method is proved to be correct. This solution is particularly useful in situations where the boundary conditions are complex, the physical properties are variable, the temperature gradient is huge ... and so on.
