摘要
从经典的定常射流理论出发,在本文提出的“等效金属罩质量”假设的基础上,提出一个估算冲击荷载荷下楔形槽表面微物质喷射量的半经验解析公式,用本公式得到的结果,与实验结果和二维HELP编码的数值计算结果做了比较,三者的符合程度比较好。这初步说明,本文提出的计算公式有一定的适用性。
Based on the classical steady-jet theory and the 'equivalent liner mass' assumption proposed by the auther, a semi-empirical analytic equation for estimating the micro-jet-ejection mass quantiiy from shocked free-surface with artificial wedged -grooves is devleped in this paper. Comparing with a few practical examples, including experimental and two-dimensional numerical simulations: it shows the semi-em -pirical equation is relatively good for utilization in rough estimation.
