| Abstract: | With the adverse thermal environment of optical window,thermal protection of optical window by the internal coolant convection is applied.In this paper,the temperature field of optical window is calculated by FEM.The results show that:computation accuracy of the method is reliable and internal coolant convection is effective on cooldown.The effect of coolant consumption on the temperature field is also given in the paper,this could be a reference standard of economical design. |
| Keywords: | optical window temperature numerical method thermal protection |
