Experimental device for the investigation of flow fields

摘要

Experimental device for the investigation of flow fields comprising • a vertical flow channel (2), • a transparent front plate (59) at the front of the flow channel (2), • an inlet opening (22) at the lower end of the flow channel (2), • an outlet opening (3 ) at the upper end of the flow channel (2), at least one test body (91) arranged in the flow channel (2) and held by at least one first holding element (92) on a wall (60) of the flow channel (2), one Circulation line (9) which is connected to the outlet opening (3) and the inlet opening (22), • a pump (15) arranged in the circulation line (9), • a flow channel (2) arranged below the test body (91), linear, the cross section of the flow channel (2) at least partially spanning, the first electrode (93) at the ends with two on a wall (60) of the flow channel (2) held second holding elements (94) ve a second electrode (44) arranged in or limiting the flow channel (2) and an electrical power supply (38.1) which is electrically connectable to the first electrode (93) and the second electrode (44) in order to connect to the first electrode (93) electrolytically generate a gas when the flow channel (2) is filled with test liquid.
