Experimental observations with ultra-speed imaging revealing new complex detail of drop separation processes from a large diameter drophead

An ultraspeed (5000 frames a second) camera has been used to record the drop separating from the photometric instrument the tensiograph. New insights into drop separation processes which have been evaluated in terms of the correction factors used in tensiometric methods for measuring surface tension...

Description
Summary:An ultraspeed (5000 frames a second) camera has been used to record the drop separating from the photometric instrument the tensiograph. New insights into drop separation processes which have been evaluated in terms of the correction factors used in tensiometric methods for measuring surface tension. An innovative approach to drop separation process drop satellite labelling is proposed and the paper ends with suggestions as to practical improvements to the photometric measurement of what is a very long-established method.
