Commencement measurements giving fundamental surface tension determinations in tensiometry
Carbery, Des; McMillan, Norman D.; Morrin, D.; O'Neill, M.; O'Rourke, B.; Pringuet, P.; Riedel, S.; Smith, S.R.P. (IOP Publishing, 2011)This study provides experimental testing of a ray-tracing model of the tensiotrace that explores the measurement potential of a well-defined optical position in the tensiotrace signal known as the 'commencement'. This point ... -
Experimental observations with ultra-speed imaging revealing new complex detail of drop separation processes from a large diameter drophead
Carbery, Des; McMillan, Norman D.; O'Neill, M.; Riedel, S.; Kennedy, D.; Nicholls, T. (IOP Publishing, 2011)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 ... -
A new optical method of continuously analysing the surface properties of a single pendant drop while obtaining quality bulk spectral and refractive index measurements of the liquid-under-test
McMillan, Norman D.; O'Rourke, B.; Morrin, D.; Pringuet, P.; Smith, S.R.P.; O'Neill, M.; Hammond, J.; Riedel, S.; Carbery, Des (IOP Publishing, 2009)The classical stalagmometer has been replaced by the tensiometer to measure surface properties from drop volume. From the drop period T1, converted into volume, the surface properties of the liquid can be obtained. In the ...
