采空区三维非稳定流场的数学模型及热力风压的计算

Mathematical Models of Unstable Air Pressure Field and Unstable Temperature Field and Heat_pressure Calculating of Three_dimension in the Goaf

在对采空区实际情况进行简化的基础上，运用多孔介质流体力学、传热学、对流传热与传质学等学科的有关原理建立了采空区三维非稳定风流场、三维非稳定温度场的数学模型，并首次推导了三维采空区热力风压的计算公式，为采空区三维非稳定流场的计算机模拟提供了理论基础．

Based on simplifying of the actual goaf and applying the related theories of porous_mediums hydrodynamics, transmitting heat, convection and conducting heat, the mathematical models of unstable air pressure field and unstable temperature field of three dimensions in the goaf have been built. At the same time, the calculating formula of heat_pressure of three_dimension has been derived for the first time, undoubtedly, it will offer theoretical basis for numerical simulation of flow field of three_dimension in goaf.
