| Abstract: |
| 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. |
