Influence of Vibration on the Temperature profile in the Liquid phase During Soliditication

He Deping;Wei Bingbo;Shu Guangji;Wang Fengquan(Southeast University,Nanjing,China)  
Stable longitudinal sinusoidal vibrations of the resonant frequen-cies of different orders of the solidification system were introduced to it toinvestigate the influence of vibrations on the temperature profile in the li-quid phase during solidification.It was found that,as compared with the caseof static solidification,the temperature profile in the liquid phase was changedand the temperature gradient was decreased due to the vibration introduced.Experiments indicate that the first order resonant frequency shows a verystriking effect.
