在不同风速下沥青路面热再生加热系统功率选择

Power Selection of Thermal Regenerative Heating System for Asphalt Pavement Under Different wind Speed

风速对红外辐射现场加热的效果有较大的影响。不同风速下,红外辐射加热系统功率的适当调整对热再生效果具有重要意义。通过Fluent软件对沥青路面红外辐射现场热再生温度场在不同风速下的变化规律进行分析,结果表明随着风速的提高,加热效果有数量关系的下降,为加热系统功率的选择提供了合理的依据。

Wind speed has great influence on the heating effect of infrared radiation field. Under different windspeeds,the proper power adjustment of infrared radiation heating system is of great importance to the thermal re-generation effect. By Fluent software for the ir radiation field of asphalt pavement thermal regeneration the changerule of temperature field under different wind speed were analyzed,and the results show that with the increase ofwind speed,the heating effect is reduced quantity relationship,for the choice of heating power system providesareasonable basis.
