Experiment and Numerical Simulation of Velocity and Temperature Fields in KNbO3 Solution
高温KNbO3熔液内速度场和温度场的实验研究及其数字模拟分析

Velocity field and temperature field in the high temperature solution in a loop-like Pt crucible were simulated numerically by using the commercial computational code under gravity conditions. The results indicate that, based on the experimental boundary conditions and the Boussinesq approximation, velocity field and temperature field with the numerical simulation basically agree with the experimental data, meantime, the fluid flow trace is also similar to the phenomena observed with the traced particles of Na2CO3 in the high temperature oxide solution.
