摘要
以普朗克定律、Mie微小粒子散射理论描述发光火焰的辐射,以彩色三基色原理描述发光火焰的辐射颜色,由此推导建立的发光火焰温度的彩色测量方法,可依据颜色数据唯一求解火焰的实际温度,而且是一种无需标定、真正意义上的温度场测量方法.彩色测温方法还从理论上揭示了发光火焰在等温条件下的颜色表现,为一条具有确定的色度坐标位置的有限长度的曲线.
A new method of temperature measurement for luminous flames,the primary color method was introduced. It is based on the Planck's law,the Mie's theory of fineparticle scatter,which describes radiation power of luminous flames,and the principles of primary colors that describe luminous color of flames.By this method,a unique temperature solution can be derived from the color data of a specific pixel in the image of a luminous flame,without calibrating the parameters of the measurement system.Therefore,it is a practical and efficient approach to measure real temperature fields of luminous flames.And in theory,this method also points out that the luminous colors at a given temperature behave as a limited curve with determined coordinates in the chromaticity diagram.
