In order to understand the impinging jet field distribution and influencing factor of printing and coating equipment oven V-shaped slot nozzle, with standard model of k-ε, numerical simulation was performed to the nozzle impinging jet on moving wall. The velocity and pressure field distribution near the moving wall was〖JP2〗 analyzed. The influencing factors of the impinging jet was considered, which include nozzle width and height, etc. The results showed that the height of the wall to nozzle and the nozzle width affect the velocity distribution near the wall evidently; considering kinds of factor, the ideal nozzle height is 15 mm, and the nozzle width is 2.5 mm.
