摘要:
在用辐射测温法研究多孔介质燃烧器中火焰温度分布时,因石英玻璃窗不能透过热象仪所能响应的火焰红外辐射波段,而不能直接测出玻璃内侧的火焰温度。该文通过对石英玻璃(属半透明介质)内热传导与热辐射耦合,边界为对流换热的数值计算,研究了石英玻璃内、外表面温度分布的变化规律的相应关联式,从而由所测石英玻璃外表面的温度分布推算出内侧多孔介质表面层的火焰分布。这种消除玻璃对测量温度影响的方法具有一定的实用意义。
Abstract:
When the f lame temper ature dist ribut ion in porous medium burner is studied by using the radiat ion measuring temperatur e metho ds, the temper ature inside the quar tz observat ion w indow could not be acquired directly by the infrared video camer a which is unable to respond the infr ar ed w av elength from the flame through the quart z. T he thermal co nduct io n coupling w ith the radiat ion w ithin the glass ( semit ransparent medium) w ith the boundar y co nditions of heat convect ion is numerical ly calculated to invest igate the variations of o ut side temperatures. From the o ut side temperature o f glass, the flame temperature in the sur face layer of porous medium can be obtained by using the relat ion calculated. T his metho d that removes the inf luence o f quart z o n measur ed f lame temperature is sig nif icant in practice.
