| 综述近似圆盘法研究轮胎的对流换热特性的进展,以期对轮胎的对流换热理论和试验研究提供参考。采用理论计算法计算圆盘的对流传热系数时,理论分析法更适用于简单工况,对数值模拟和试验测试具有重要的指导作用,但在复杂工况下很难求得对流换热方程的解析解;数值模拟计算流体动力学(CFD)法能够处理复杂的边界条件和计算流动特性,对复杂的对流换热特性能给出数值解和可视化结果。采用试验测试法测量圆盘的对流传热系数时,加热板法可以直接测量对流传热系数,提供直观的准确数据,并通过电机控制圆盘旋转,增强试验的可控性和灵活性,适用于多种流体和试验条件,但该法需要较多设备,成本较高,达到稳态的时间长,存在热量损失问题,且设备老化可能影响数据精度;萘升华法适用于轮胎表面的对流换热特性研究,但该法的计算复杂,萘在试样表面分布的均匀性难以保证,且萘的气味涉及安全和环保问题,其量化过程中存在的误差导致测试精度较低。未来需开发应用于不同花纹轮胎以及轮胎与路面、轮胎与空气不同相互作用的CFD模型,同时还需开发相应的测试技术。 |

| The progress in the study of the convection heat transfer characteristics of tire using the approximate disk method was summarized,aiming to provide referance for the convection heat transfer theoretical and experimental studies of tire.When calculating the convective heat transfer coefficient of the disk through theoretical calculation method,the theoretical analytical method was more suitable for simple conditions and offerred important theoretical guidance for numerical simulation and experimental test.However,theoretical analytical method was difficult to obtain analytical soluations for convective heat transfer equations under complex operating conditions,while numerical simulation computational fluid dynamics(CFD) methods could handle intricate boundary conditions and calculatated flow characteristics,providing numerical solutions and visualization results for intricate convective heat transfer equations.When measuring the convective heat transfer coefficient of the disk through experimental testing method,the heating plate method could directly measure the convective heat transfer coefficient,providing intuitive and accurate data.By controlling the disk rotation with a motor,the heating plate methed enhanced experimental controllability and flexibility,making it suitable for various fluids and test conditions.However,this method required extensive equipment,resulting in higher costs.Additionally,it took a long time to reach steady-state conditions,with heat loss issues,and its experience data accuracy was reduced due to equipment aging.The naphthalene sublimation method was applicable for studying convective heat transfer characteristics of tire surface,but its calculations were complex,and the distribution uniformity of naphthalene on the sample surface was difficult to ensure.Moreover,the odor of naphthalene involved safety and environmental issues,and the errors in its quantification process led to low measuring accuracy.In the future,it was necessary to develop CFD models applicable to various pattern tires,as well as the interactions between tire and road surface and tire and air,at the same time,corresponding measuring techniques also needed to be developed. |
