Dynamic mode decomposition of thermocapillary convection in GaAs melt liquid bridge between unequal ends
INTERNATIONAL JOURNAL OF HEAT AND MASS TRANSFER(2023)
摘要
•The type of the first bifurcation of the liquid bridge between equal ends is an oscillation bifurcation, but the static bifurcation is found in the liquid bridge between unequal ends.•As the radius ratio decreases, the stability of the gallium arsenide liquid bridge thermocapillary convection first weakens and then gradually improves.•The results obtained using the DMD algorithm provide evidence for the existence of mixed modes with different wave numbers.
