The effect of rotation on thermal convection in a Czochralski configuration with a heated crucible bottom is investigated through 3D numerical simulations. Without rotation, a three‐dimensional stable flow represented as a spoke pattern appears. With the crystal rotation, the spoke pattern gives way to the curving streaks, which travel in the azimuthal direction. For relatively high rotation rates, the rotation‐thermocapillary‐induced convection is dominant. This is reported by Chun‐Mei Wu and co‐workers in article number 1700268 .
