Analyses of surface treatment effectiveness using rotational multi-orifice nozzles are presented in the paper. Theoretical models of such jet traces distribution during flat surface treatment operations are presented too. Criteria of after-treatment traces distributions and their influence on rotational nozzles kinematics are also discussed in. Presented analytical results point out an influence of such most important kinematical parameters like: traces width, rotational velocity and feed rate of nozzles equipped with different orifices number, on such kind surface treatment efficiency.
