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,从而建立一系列条件下的初始释放瓦斯膨胀能数据库;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。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,能够满足工程实际需要。
Orthogonal experiment was used to conduct a series of experiments on the initial release of gas expansion energy in dead space to establish an initial database of released gas expansion energy under a series of conditions. Based on the theory of thermodynamics and fluid mechanics, it was deduced that under certain temperature and gas pressure, Space volume and other conditions, the dead space in the coal sample tank gushes out the initial release of gas expansion energy calculation expression. Based on this, some experimental values are verified, and the difference between the theoretical and experimental values is small, which can meet the actual needs of the project.
