利用舰船红外辐射强度数学模型,对基于声学方法的舰船烟囱红外辐射强度测量技术的影响因素进行了仿真研究,结果表明:烟气的热物性参数,红外辐射源的辐射特性以及环境噪声是影响红外辐射强度监测的主要因素.其中烟气的比热比的影响最大,其次是辐射源的发射率和环境噪声.准确确定烟气比热比,辐射源的发射率以及设法降低环境噪声是提高舰船红外辐射强度的重要手段.

A simulation study was made to analyze the effecting factor on the infrared radiation calculation for naval ship chimney using the mathematical model of the infrared radiation intensity.The simulation results indicated that there are three main effecting factors on radiation intensity,including thermal parameters of flue gas,radiative parameter of infrared radiation object and noises of environments.The ratio of specific heat has the most effect followed by emissivity of radiative object and noises.To reduce infrared radiation,it was necessary to confirm the ratio of specific heat,emissivity and depressing noise.
