Investigation of flow around models in laminar, two-dimensional flow using ink as contrast medium Features - visualisation of streamlines - ink as a contrast medium - various models included: drag bodies and changes in cross-section - sources and sinks, individually or in combination Learning objectives/experiments - visualisation of streamlines in -- flow around drag bodies -- flow through changes in cross-section - influence of sources and sinks Specification [1] visualisation of streamlines [2] water as flowing medium and ink as contrast medium [3] upper glass plate, hinged for interchanging models [4] bottom plate with water connections for generating sources/sinks [5] sources/sinks can be combined as required [6] different drag bodies and changes in cross-section included [7] rubber plate for creating your own models included [8] flow velocity, water supply and water drain in sources/sinks as well as dosage of the contrast medium can be adjusted by using valves [9] water supply using HM 150 base module or via laboratory supply Technical data Flow chamber contains two plates - distance between the plates: 2mm - upper plate made of glass - bottom glass plate with four water connections for sources/sinks - size experiment area: LxW: 400x280mm 10 drag bodies and changes in cross-section Rubber plate for your own models - LxH: 300x400mm - thickness: 2mm Injection of the contrast medium (ink) - 15 holes Tank for contrast medium: 500mL LxWxH: 640x520x520mm Weight: approx. 24kg
