| 摘 要： | 通过实验找出微热光电系统燃烧室在最优影响因素下的各测温点的温度值,用灰色系统理论对其建立灰色预测模型,预测最高温度值所处位置.由普朗克定律可知:温度值的高位变动对辐射力产生的影响要比低位变动大.突扩台加工位置从壁面温度的最高点处开始,既增加了微热光电系统燃烧室外壁面最大温度值,又减缓了壁面温度的最大值到出口处的温度分布,对提高微型热光电系统的热电转化效率有显著作用.

| Abstract: | The temperature at measuring points of micro-thermophotovoltaic combustor with the best influence factors was identified in the test,and the grey prediction model was used to forecast the position of the highest temperature,which was established with the gray system theory.From the Planck's law of radiation,high variation of temperature will have a greater influence on the radiation force than low variation.Sudden expansion structure is selected at the peak position of wall temperature,to further increase t... |
