| 摘 要： | 通过利用热力学和流体力学理论推导出,在一定的温度、瓦斯压力与死空间体积等条件下,煤样罐内死空间涌出的初始释放瓦斯膨胀能的计算表达式;应用正交实验法进行一系列死空间初始释放瓦斯膨胀能实验,基于MATLAB软件建立一系列条件下的该实验数据库,据此验证一些实验测定的数值,经对比理论值和实验值,两者差距较小,很好的满足工程需要。

| Abstract: | Based on thermodynamics and fluid mechanics theory,under certain condition: Temperature,gas pressure and dead space volume and so on,the calculation expression of initial release of gas expansion energy which the dead space of coal tank emission is derived;Used orthogonal experiment method,a series of the initial release of gas expansion testes which dead space gushed out had been done,based on MATLAB-software,a series of experiments database was established under a lot of conditions,Accordingly,some experi... |
