Abstract Scope |
Electromagnetic levitation experiments provide a powerful tool that allows for the study of nucleation, solidification and growth in a containerless processing environment. However, in experiments using the oscillating drop method, it is important to understand the magnetohydrodynamic flow within the sample to ensure valid measurements. In opaque liquid metal drops it is not usually possible to directly measure and characterize the flow within the drop; however, the flow can be indirectly measured through modeling which relates the experimental parameters with the thermophysical properties to calculate the properties of the flow. To ensure clean measurements, modeling should be done during the design phase to evaluate the experimental parameters and the resulting flow. This will allow parameters to be restricted to a range that will provide flow that will result in valid measurements. |
