Hot-wire series response equations were derived for the measurement of turbulent flow by an X-probe from the generalized hot-wire response equation at an arbitrary angle. Based on the experimental results for a circular free jet, the turbulence velocities of the jet were shown not to be completely included inside the convergence domain of Taylor's series response equations for an X-probe. Assuming a normal distribution for the turbulence velocities of the jet, the validity of the correction of the effect of the yaw factor on the measured values of the Reynolds stresses was discussed based on the numerical experiment. The optimum number of terms of the series response equations to obtain the most accurate Reynolds stresses was also numerically determined.
