摘要
本文在当地化假定下,应用连续流和自由分子流加权平均方法给出过渡流动区域的压力和切向力公式,应用回归拟合方法确定权函数中待定常数,计算了绕物体流动的气动力特性。计算结果表明,本文能够得到符合工程要求的气动力结果。
Under the assumption of the localization,the formula of pressure and tan-getial stress in the transition flow regions are prestented using the weighted average method over continious flow and free molecular flow. The undetermined constants of the weighted functions are obtained by regression analysis to evaluate the aerodynamic properties of the flow over a blunt body. The results obtained by the engineering evaluating method presented in this paper are compared with the experimental result consistently.
