Abstract :
The investigations of kinematic and dynamic characteristics of electrohydrodynamics flows (EHD) in full interval of voltage scale (i.e. from threshold of beginning to breakdown of the gap between electrodes) in electrode system wire-plate, sphere-plate in 10% solution of buthanol in transformer and castor oil was described. The experimental apparatus, which contain three canals-optical, electronic and pneumatic, was made. For the measurement of velocity of EHD-flows tiny bubbles of air are used, which served as light-dispersal marks. The flow was divided between developed and undeveloped flows
