Study on different line gasoline blending with RJM via numerical investigation

Abstract

The blending effect of gasoline is numerically simulated with different angles of nozzles and rotation speeds based on a rotary jet mixing (RJM) system. The outlet of the RJM system might destroy the components of gasoline, therefore an extra component is firstly added when the RJM system was established. In order to increase the accuracy of the simulation, sliding grid technology is applied and the meshes are divided into different sizes. The radial velocity attenuation curves and Center dynamic pressure attenuation curves of horizontal nozzles, the distribution curves of the cross-section velocity, and velocity nephograms of different blending flow fields were obtained. The results show that the jet property of nozzles and the mixing performance of the RJM system and it can effectively improve the mixing efficiency.
