<p>Synchronized measurements of the velocity and temperature fields in a zero-pressure gradient turbulent boundary layer over a heated flat plate were conducted using a cold-hot dual-wire probe calibrated across various temperatures and velocities. A comparison with direct numerical simulation results demonstrated the accuracy of the cold-hot dual-wire probe in measuring velocity within flow fields characterized by significant temperature fluctuations. Additionally, the theoretical frequency response curve of the cold-wire was used to simulate the temperature fluctuation signals measured by cold-wires of different diameters and lengths. The results suggest that using a 5 µm cold-wire instead of thinner ones is a highly cost-effective choice. Finally, based on the strong correlation between the velocity and temperature fields within the thermal boundary layer, we proposed a method to correct temperature effects using the hot-wire signal alone, without cold-wire temperature measurements. Using hot-wire anemometry, the self-correction method can effectively correct the impact of temperature gradients on mean velocity measurements. However, its effectiveness in managing fluctuating temperatures is less than that of the direct measurement method using a cold-hot dual-wire setup. The velocity root-mean-square values obtained with this method have an error of less than 5% in the logarithmic region. This method is a viable alternative when a cold-wire is unavailable.</p>
