【摘要】 以相似理论为基础,对KBN双通道燃烧器出口湍流场进行了研究,通过因次分析得到了可视化模拟的相似准则。并采用了酸碱水模拟可视化方法,对出口燃烧影响比较大的燃料和燃烧空气的混合情况进行了可视化模拟,验证了所得到的可视化模拟条件的正确性。更多还原

【Abstract】 With study on turbulent flow produced by the KBN 2channel burner and the theory of similarity the criteria of visualized simulation were obtained by factor analysis method.The effect of mixing the fuel and air at the burner’s exit which influences strongly on burning was simulated by the acid/alkali liquid visualized model.By this visualized simulation experiment these criteria are validated accurately.更多还原
