Vertical Visualisation Of Flow Fields

Product Description

Vertical Visualisation Of Flow FieldsFine gas bubbles are perfectly suited to visualising flow fields. Due to analogies, many flow processes that occur in air can also be demonstrated by experiments in water.The trainer consists of a vertical experimental section in which an interchangeable model is inserted. Water flows from bottom to top through the experimental section. Electrolytically generated hydrogen bubbles rise with the flow, flow around the model and visualise the flow. Different models are available: drag bodies (e.g. aerofoils and cylinders) or changes in cross-sections.Learning Objectives And Experiments Visualisation of two-dimensional flowsStreamline course in flow around and through modelsFlow separationVortex formation, demonstration of Karman vorticesQualitative observation of the velocity distribution in laminar flowAnalogy to air flow Specification Electrolytically generated hydrogen bubbles visualise flow fields of different modelsClosed water circuit with experimental section, storage tank, pump, valve to adjust the flow velocityVertical experimental section with black background, LED illumination on both sides and 2 insert positions for the modelLow-turbulence flow using stabilisation tank with flow straightenerBubble generator: platinum wire as cathode and frame of experimental section as anodeCathode can be inserted in different positionsSetting cathode current, pulse and pause durationSwitch cabinet with displays for cathode current and flow velocity
