Beeswax has demonstrated significant potential as a renewable solid fuel for hybrid rocket
propulsion due to its biodegradability, high regression rate and combustion performance.
However, the behavior of molten beeswax during microgravity operation remains difficult
to predict, limiting the ability to optimize centrifugal casting systems before flight. This
research addresses this challenge through the development of a multiphysics digital twin
capable of predicting the mechanical, thermal, and fluid behavior of a motor-driven centrifugal
casting experiment in a microgravity environment. The completed framework combines
electromechanical modeling, transient thermal analysis, and control system simulation to
evaluate motor dynamics, power consumption, heat transfer, and beeswax phase change under
representative operating conditions. The mechanical model was validated against experimental
motor data, demonstrating less than 2% error, while the thermal model successfully predicts
transient temperature distribution and melting behavior throughout the casting system. Together,
these models provide a computational platform for evaluating system performance and reducing
the need for costly flight-based design iterations. The next phase of this research will integrate
computational fluid dynamics (CFD) to simulate molten beeswax flow, free-surface evolution,
and material redistribution, enabling prediction of casting uniformity and supporting the
development of reliable microgravity manufacturing technologies.
