The role of geometry on controlled cavity collapse and top jet drop

The contents of this work explore the influence three geometric parameters on controlled cavity collapse at liquid interface and subsequent ejected drop; are angle ejecting nozzle plate (θ), height (H), radius (R) vessel used to enclose within. conducted computational modeling shows that changing from a flat surface inclined in one direction causes droplet diameter decrease, whereas an inclination opposite results larger droplets. Moreover, fluid does not actually drop size its velocity as long is much than (R 0 ). Below limit H = 5R , starts decrease increase by decreasing height. Finally, decreases increasing even when R ≫ . This attributed change displaced volume subsequently tip changed.
