The new hot-wire method of the simultaneous measurement of concentration and TWO velocity components for CO_2-air mixture has been developed. In this method, two hot-wire probes (X type hot-wire probes) with low OHR and one hot-wire probe (I type hot-wire probe) with OHR used in the past work by Chassaing (1979)^<1)> have been used. The values of the instantaneous concentration and two velocity components can be determined from the output voltages of three hot-wire probes. The measurements have been performed in case of the CO2 jet in the grid turbulence. The experimental results showed that the axial and radial distributions of the mean and r.m.s. values of concentration and velocity, and axial mass flux agree well with the past other data.
