AFF049 Characteristics Of Nozzles Fluids Engineering Training Equipment Educational Equipment Teaching Equipment
Learning Objectives / Experiments
- determining the critical pressure ratio
- demonstration of the "choking effect"
- determining flow velocity in the narrowest cross section
- measurement of the reaction or action force of the flowing fluid
- determine nozzle efficiency by thrust
Specification
[1] detect impact force or thrust at nozzle to determine the flow velocity and nozzle efficiency
[2] experiment layout A: measuring reaction force (thrust) of the fluid at the nozzle
[3] experiment layout B: measuring action force of the fluid at the baffle plate
[4] air intake adaptable according to the experiment layout
[5] distance between baffle plate and nozzle can be adjusted
[6] compressed air regulator for adjusting the pressure downstream of the nozzle
[7] needle valve on the flow meter for adjusting theback pressure
[8] measuring reaction or action force of the nozzle by deformation of the bending beam
[9] 5 nozzles with different contours (4 convergent divergent, 1 convergent) and 1 baffle plate
[10] instruments: manometer and digital temperature display upstream and downstream of the nozzle, as
well as rotameter
