Momentum time derivative evaluated inside the inner flow field (including the solid particle) plotted as a function of time. Black circles are from dynamic simulation and red dashed curve is fitted from Eq. (1212). Inset shows the corresponding electric field as a function of time. It shows a linear increase within 5 × 10−8 s to reach the saturation level.
