氧-乙炔烧蚀试验中热流密度的计算

摘要

Patterns of heat flux density with the different flux ratios of oxygen to acetylene in oxyacetylene flame test was researched. And the mathematic relations between heat flux density and flux ratio of oxygen to acetylene had been establishedi in different scopes using simple linear regression. Being verified, the relation is very applicable and can be used to provide credible references on changing heat flux density in oxyacetylene flame test of heat-shielding composite.%通过氧-乙炔烧蚀试验中改变氧气与乙炔气流量比值的一系列试验,研究了热流密度随其变化的规律,并利用一元线性回归方法,分区间拟合得到了热流密度与两种气体流量比值的数学关系式,经检验该关系式适用性较好,为防热复合材料在氧-乙炔烧蚀试验中热流密度的变化提供了可靠的计算依据.
