本文提出了用Bohning/Doerffer定律模拟多孔板流动的方法。它提供了发汗边界条件的数值模拟，已成功地用于激波/边界层干扰控制。该法律的细节以易于在现有求解器中实现的形式提供。详细讨论了背景实验及其分析。该定律的新特点是能够考虑切向流沿沿着多孔壁流动的影响。发汗定律的公式化与确定多孔板空气动力特性的方法的发展有关。提出了一种确定发汗定律中必须用到的“气动孔隙率”的方法。蒸腾问题如何建模是互补处理，并提供了一个描述的流动行为与孔隙度确定的方法。这种方法为数值模拟和实验研究提供了一种耦合的方法。(C)2000年，Elsevier SAS科学与医学版。
This paper presents the Bohning/Doerffer law for the modelling of the flow through a perforated plate. It provides the transpiration boundary condition for numerical simulations which have been successfully used at shock wave/boundary layer interaction control. The details of the law are provided in a form that is easy for implementation in existing solvers. The background experiments and their analysis are discussed in detail. The new quality of the law is the ability to take into account the effect of a tangential stream flowing along a porous wall.Formulation of the transpiration law was associated with the development of a method for the determination of a porous plate's aerodynamic properties. A method is presented to determine the 'aerodynamic porosity', which must be used in the transpiration law. The problem of transpiration how modelling is treated complementarily and provides a description of flow behaviour together with the method of porosity determination. This way the coupling of numerical simulation and experiment has been provided. (C) 2000 Editions scientifiques et medicales Elsevier SAS.
