Abstract
The formation of gas film on the wall is a common method in industrial manufacture to prolong life-span of equipment and improve the product quality. In this research, simulations considering the formation of gas film in the radial multiple jets-in-crossflow (RMJC) reactor were carried out, the influence of distance between the center of jet holes and film holes (djf) as well as the angle between film holes (φ) on the formation of gas film have been discussed with varying blowing ration γ. The simulation results show that when the applied γ is at the critical value (0.08), a stable and continue gas film could be obtained and a good mixing performance of reactor could be hold. Moreover, some optimizations of reactor geometry structure on the basis of γ were made. It was found that when γ gets to the critical value, small djf and φ are better choices while a large djf is preferred when γ is below the critical value. This research is meaningful in facilitating the formation of a steady and lasting gas film in the RMJC reactor.
