<p>The internal flow field and thermal field of droplets affects the levitation state and the accuracy of the thermophysical property measurements. While, there have been no reports on the distribution of flow field and temperature field in Fe-Cr-C alloy droplets. This work studies the distribution and evolution of the flow field and temperature field in Fe-Cr-C alloy droplets under different levitation current and levitation frequency. The results shows that: the levitation current increases from 360 to 590 A, the maximum flow velocity within the droplet increases from 0.440 to 0.487 m/s and the maximum temperature increased from 1935.55 K to 2268.30 K. The absolute value of the maximum flow velocity of the large vortex on the longitudinal center line is twice the absolute value of the small vortex flow at the bottom. The temperature distribution on the longitudinal centerline of the droplet includes three stages. The increase of levitation frequency from 290 to 340 kHz has a little a negative correlation on the droplet's flow velocity and shear rate. Meanwhile, the maximum temperature increased from 2090.74 K to 2094.23 K, and the temperature of the droplet only increased by about 4 K.</p>
