The present study is an experimental investigation of compressible jet flow from a pipe with a hexagonal cross-section. The pipe is fixed to a settling chamber which is supplied with compressed air by a storage tank via a pressure regulator. The experimental methodology includes the measurement of centreline variation of stagnation pressure and the visualization of shock structures. The results from the present pipe shape considered for the present study will be compared with the results of jet flow experiments from a circular pipe. The diameter of the circular pipe is taken as 15mm and the same is fixed for the hexagonal pipe. The L/D ratio of the pipe is chosen as 5. The nozzle pressure ratio will be varied according to the source available and the measurements will be taken via a Pitot tube connected to a Pressure Scanner. The positioning is controlled by a traverse mechanism which can move in axial and transverse directions. The results obtained will be discussed in detail with the help of relevant literature.
