摘要
运用流体粘滞阻力公式,对Re<1,103<Re<105等情况下自由落体的流体粘滞阻力作了推导;通过实验及数值模拟法研究了理想锥体不同锥角、不同母线的自由下落过程,实验结果与理论推导基本吻合,时间误差为0.04 s.

Abstract:
By using fluid viscous resistance formula of ideal cone into free-fall were studied in Re<1,103<Re<105.Through experimen and numerical stimulation study the ideal in different angles and cone free fall under different generatrix.The restult of experiment agrees quite well with the therorectical derivatione.Time error is 0.04 seconds.
