Computational Assessment on Molten Metal Fluidity in Casting Process by Ultrasonic-Assisted Vibration

The fluidity of the molten metal during the casting process is essential as it has a direct effect on the integrity and quality of the cast components. High fluidity by UAV approach speeds up production, increases surface smoothness, and lowers faults by reducing surface tension, minimizing flow resistance. It also avoids incomplete mold filling by facilitating a correct and uniform flow of the molten metal. In this study, during pouring, several ultrasonic frequencies were applied to find out the impact on the fluidity of molten metal in different types of mold design. To determine the optimal frequency that promotes fluidity while reducing turbulence, flow disturbances were evaluated to assess their effects on flow behavior, filling efficiency, and flow resistance throughout the casting process. It has been observed that application of ultrasonic frequencies improves metal fluidity and lower flow resistance.
