Description
Summary:碩士 === 國立成功大學 === 材料科學及工程學系 === 102 === In the present work, commercial software packages ANSYS Fluent and ANSYS Mechanical are used for simulating the molten steel flow under the effect of magnetic field inside the mold. The reliability of the numerical models is verified using a comparison with results from experiments of physical models. Good agreement is found between the predictions and experimental results. Then the verified models are used to analysis two kinds of electro-magnetic technique, electromagnetic stirring (EMS) and electromagnetic braking (EMBR). The difference between velocity fields inside the mold with and without electromagnetic field is discussed. The results show that EMS are able to accelerate the flow velocity of the molten steel but the stirring ability will be limited due to the design of funnel type mold. On the other hand, EMBR can be well functioned if the maximum magnetic flux density is set to an appropriate value. The proposed models can be helpful to figure out this value.
