| Abstract: | Based on forced draught cooling system on heated coating, the paper discusses the research actuality of impacting jet. With the computational equation of Nusselt number based on experiments for times and existing research achievements on heat transfer, the mathematical model is built, which provides theory basis for the studying of forced draught cooling. Furthermore, it uses the software of fluent to make the numerical simulation, and get the temperature field, which is also a verification of the mathematical model. |
