Note (General): The flow turbulence level of the NAL two-dimensional transonic wind tunnel was measured with a constant temperature hot-wire anemometer using a hot film probe. The fluctuation of the mass flow is within a range of 0.3％-0.45％ with Mach numbers of 0.2 to 0.8 and unit Reynolds numbers of 1.8×10(exp 5) to 5.5×10(exp 5) (1/cm). The fluctuation of the total temperature was one-seventh to one-tenth of the mass flow fluctuation. A plain sound wave was assumed, and the noise data was measured simultaneously with the turbulence and compared with this turbulence. An attempt was made to separate the velocity fluctuation and the density fluctuation in the mass flow. The future development of this complex method is discussed in this paper.
