Research on Power Control Mode of Hot-air Heater Based on Fluent
To address the problem that fan assembly com-ponents are damaged due to high temperature of the circulating air during heating of the asphalt pavement by a hot-air heater,software Fluent is used to establish a simulation model to simulate the operation process of heating the asphalt pavement by the heating unit.At the same time,the original power control strategy of the heater is optimized,and through compar-ison with the field test data,the correctness of the model is verified.The research results show that,the heating unit adopting the optimized power control strategy cannot only ensure the quality of pavement heating,but also effectively improve the temperature of the circulating air at the fan assembly while meeting the construc-tion standards.
