- This paper reports on the MEDI microgravity experiment flown on the MASER 13 rocket. Uniquely, this experiment provided real-time data on poly-crystalline equiaxed solidification. A novel computer model of the experiment was developed and applied. The model simulated the true nature of the thermal conditions. A novel feature included the application of a fast algorithm to the evolving latent heat for athermal poly-crystalline nucleation and growth. This significant work led directly to a new modelling technique called the Nucleation Progenitor Function approach (published subsequently) and to continuous funding (EPSRC-feasibility: NUPRO project). Impacts are expected in grain refinement and other areas.
