High-strength transient heater is used in aviation、aerospace、weapons、shipbuilding and other industries.When the design is unreasonable,it will cause materials to fail and affect the heat performance.In severe cases,it will cause explosion accidents and destroy related equipment.Therefore,it is necessary to analyze the heat flow field of the High-strength transient heater.In the first,the exploratory experiments were completed in this paper,assumptions and theoretical analysis of the high-strength transient heater were performed based on the exploratory experiments.The preliminary design of the high-strength transient heater was completed and the design was processed to obtain a real object.Secondly,the closed explosive device experiment of high-strength transient heater was completed,and the temperature and pressure data of the reference position were obtained.The numerical research of this experiment was carried on,and the heat flow characteristics in this experiment were analyzed by comparing the experimental and numerical results.The accuracy of the numerical models and parameters used was verified.Finally,the temperature measurement experiment of the high-strength transient heater under actual working conditions was completed.The numerical research of this experiment was carried on and new experimental data was obtained.Compared it with the numerical results,the conclusion was drawn that the high-strength transient heater meets the engineering requirements.Through the combination of experiment and numerical study,the heat flow field of the high-strength transient heater was analyzed,and the heat transfer performance of the high-strength transient heater was evaluated in this paper.At the same time,the error between the experimental results and the numerical results is within the allowable range of the project,indicating the accuracy of the numerical analysis.The analysis shows that under the impact of high heat flux,the high-strength transient heater has a good structure,and the key components have no obvious damage.The entire heater can quickly reach the required temperature within the corresponding time to meet its working requirements.The experimental results are in good agreement with the results of the numerical studies.The results are credible and provide a basis for the design and analysis of similar heaters. |
