| 摘要: | 本文整理利用一階準確的Lax-方法分析 在可移動砲管內的氣-固二相流的物性。本文 是在一維的空間上運作並採用二相共存的模式 。Nobel-Abel氣體方程式及其他的合成律在本文中使用。所發展的程式用以預測在砲管內的 壓力形成及固態火藥的燃燒。
This paper presents the preliminary results, using first-order Lax finite difference scheme, to study the gas-solid combustion physics in a gun tube with a mobile projectile. One dimensional analysis is conducted for the time being. Space-sharing interspersed continual assumption is made in this study. Noble-Abel gas equation of state, molecular viscosity and thermal conductivity, interphase drag, heat transfer relation, and burning rate correlation for propellants form a set of constitutive equation. The developing computer code is used to predict the pressure wave build-up and flame front acceleration existing in a gun barrel full granulated solid propellants. |
