Simulation study on the influence of waveguide end distance to microwave heating efficiency

波导口距离是影响微波加热沥青混合料效率的重要因素.为了提高微波加热沥青混合料的效率,利用CST软件分别对2.45GHz和5.8GHz频率微波加热沥青混合料时波导口距离对加热效率的影响进行了仿真研究.通过对两种频率下功率损耗密度随波导口距离变化趋势的分析,得出了两种频率下微波加热沥青混合料的最佳波导口距离.

The waveguide end distance is an important factor that affects the efficiency of microwave heating asphalt mixture. In order to improve the efficiency of microwave heating asphalt mixture, the CST software simulation was used to study the influence of waveguide end distance to heating efficiency when 2.45 GHz and 5.8 GHz microwave heating asphalt mixture. By means of the analysis of the movement direction of the power loss density with the waveguide end distance,the optimal waveguide end distance when the two frequency microwave heating asphalt mixture are obtained.
