ZM7156 Visualisation of Flow Fields Educational Equipment School Equipment Teaching Bed Fluid Mechanics Lab Equipment
visualisation of flow fields by using electrolytically generated hydrogen bubbles
platinum wire as cathode and stainless steel plate as anode for electrolysis
shallow water channel fitted with indirect LED illumination along the experimental section 
various models are included: aerofoil, rectangle, straight plate, curved plate, cylinder (various sizes), various models for changes in cross section
flow straightener and glass balls ensure consistent and low-turbulence flow
different flow velocities via variable-speed circulating pump 
setting power (with display), pulse and pause length of the power and the flow velocity in the water channel
