Hot-wire based estimation of pressure fluctuations in the near field of a jet in the presence of a co-flow
O. P. Bychkov, G. A. Faranosov
It is shown that the velocity fluctuation spectra measured using a hot-wire in the potential flow region of a turbulent jet near field in the presence of a co-flow can be converted…
