      Using the area ratio and the length to width ratio, the design was checked against a chart of diffuser flow regimes from Japikse’s book, “Introduction to Turbomachinery” (Figure 5). The redesigned diffuser falls in the region of “no appreciable stall” which indicates that the diffuser will function nearly ideally. This condition governs the transfer of energy between the acoustic field and the flow field. Sound absorption by vorticity shedding The presence of mean flow in the pipe influences the rate of sound radiated to the far field. The results presented in Figure 5 show that acoustic losses due to vorticity is. 16 dominantly a low frequency process.

Little evidence of the first vortex pair remains at the exit of the diffusing bend. The mass-averaged total pressure loss is found to be insensitive to the range of inlet-flow variations considered herein. However, the rate of generation of this loss along the length of the diffusing bend differs between the two test by: 7.

Schiffer, Investigation of unsteady flow behaviour in transonic compressor rotors with LES and PIV by: 1. One of the main properties of a turbulent flow under identical initial- and boundary conditions is that the flow is asymptotic, which means they are identical in the mean flow characteristics.

Assuming a potential flow, this can be used for turbulent flows to. Also, the flow field for this case has never been measured. The present study makes these flow field measurements using a custom PIV setup, and also makes force measurements using a custom force balance.

The flow field measurements measure the recirculating flow in the bubble, and average profiles are constructed downstream of.
