Product Code : SCL-CELE-14159
Overview
The Nozzle Flow and Pressure Distribution
Apparatus enables the study of pressure and velocity variations in convergent
and convergent-divergent (De Laval) nozzles using compressed air
as a working medium.
The unit allows visualization of subsonic, supersonic, and shock wave
phenomena as well as the choking effect, where the mass flow ceases
to increase beyond the critical pressure ratio.
By recording the pressure distribution
along the nozzle axis at multiple measurement points, students can analyze the flow
behavior of compressible fluids and correlate it with theoretical models.
The setup includes three interchangeable
nozzles (one convergent and two De Laval types with different lengths), a compressed
air regulator, and precision instruments for measuring pressure,
temperature, and mass flow rate.
