The trajectory and penetration of liquid jet in crossflow with non-uniform velocity distribution were studied experimentally. Using specifically designed perforated plates to realize several non-uniform velocity distributions, water was used as the jet liquid, and the research was carried out by laser sheet combined with phase doppler particle Analyzer. The main concerns involved the average jet momentum flux ratio, the local Weber number and non-uniformity of the transverse velocity distribution. The influence of the crossflow with non-uniform velocity distribution on the liquid jet was mainly reflected in the transformation of the breakup mode along the liquid flow direction.
