Dynamics of a successive train of monodispersed millimetric-sized droplets impact on solid surfaces at low Weber number

• A piezoelectric droplet generator was designed and fabricated. • Results of the droplet train impact were recorded by a high-speed camera. • The comparison has been made with the single droplet impact to understand the difference in mechanism. • Effect of impact frequency, Weber number, and surfac...

• A piezoelectric droplet generator was designed and fabricated. • Results of the droplet train impact were recorded by a high-speed camera. • The comparison has been made with the single droplet impact to understand the difference in mechanism. • Effect of impact frequency, Weber number, and surface static contact angle have investigated and relevant empirical correlations were obtained.
