Study on Size Selections of the Ten-Needle Inline Nozzle Structure

The main objective of this study is to select the reasonable parameters for the ten-needle inline nozzle structure. Its internal flow fields were simulated by using FLUENT software. Quadrature calculations are conducted according to different inlet flow, different diameters and different lengths of the needles. The partial flow and drift rates under different inlet fluxes were analyzed. Through curve fitting method, the size ranges of the optimal structure under different conditions are obtained.
