钝体绕流及其燃烧特性的研究

Analysis of Bluff Body in Cross Flow and Its Characteristics on Combustion

在火灾中常见到一些钝体可燃物，与迎风面相比，其背风面烧毁的程度要严重得多，以及仅在背风面有过火痕迹等燃烧现象，如森林火灾中的树干，建筑火灾中的柱体也有类似问题。本文针对这些火灾特性，进行了钝体绕流及其燃烧特性的实验和计算机模拟研究。

In forest fires,it is often encountered that flame spread characteristics on adverse wind side of tree could be maintained and the damage of tree on adverse wind side is more serious than that on towards wind side.The paper is to study the typical characteristics about the combustible bluff body by the methods of the experiment and the numerical computation.
