| Abstract: | Aerosol jet dynamic heat transfer experimental facility was designed and constructed independently. The model of 2 - d inverse heat conduction problem in unsteady state was studed. The time distribution of surface temperature and surface heat flux density were analyzed. The results showed that while the cylinder covered several different heat transfer stage in the process of cooling in the flowing jet area and water area, the temperature curve appeared periodic characteristic obviously. The periodic characteristics of the heat transfer by aerosol jet cooling of the secondary cooling of continuous casting were simulated successfully. |
