Technical Description
The experimental set-up consists of 2 tapered inserts with which a continuous constriction of the measuring section in the wind tunnel is created. The dynamic and static pressure are measured using a Prandtl tube. During the experiments, the Prandtl tube is moved from the start of the constriction to the narrowest point, in this way the pressure as a function of position is measured. The apertures are fixed to the side walls of the measuring section using bolts, the Prandtl tube is placed in an opening on the bottom of the measuring section and moved along a slot in this position. The position of the probe can be read off in a scale beside the slot.
Learning Objectives / Experiments
The continuity equation and the energy equation (Bernoulli) can be checked in experiments:
· Measurement of the dynamic pressure component on constriction of the flow cross-section
· Measurement of the static pressure component, related to atmospheric pressure
