应用紊流三维数学模型模拟内燃式热风炉内冷风在格子砖柱中的分布，寻求改善其分布的途径 讨论了加设不同布置的水平导流板对气流分布的影响 模拟结果表明，在支柱空腔内加设水平导流板改变了原有大回旋流场，使回旋流变成大面积的单向流 通过在支柱空腔内加设水平导流板可以发展边缘气流，这恰好与加设竖直导流板的作用相反，水平导流板和竖直导流板的结合使用有望实现冷风在格子砖柱中的均匀分布
The application of turbulence three-dimensional mathematical model to simulate the distribution of cold wind in the lattice-type brick in internal combustion hot blast stove and seek ways to improve its distribution The influence of horizontal baffles with different layout on the gas flow distribution is discussed The simulation results show that Addition of a horizontal baffle in the column cavity changes the original large swirling flow field and makes the swirling flow into a large area unidirectional flow. The edge airflow can be developed by adding a horizontal baffle in the stanchion cavity, which is exactly Contrary to the function of vertical baffle, the combined use of horizontal baffle and vertical baffle is expected to achieve the uniform distribution of cold wind in the checkerboard.
