Abstract

Thanks to ubiquitous availability of high-performance computing (HPC), there is an increasing demand towards developing numerical models and methods for simulation of multiphysics problems. This presentation provides a brief overview of some of the innovative ways to achieve predictivity with practical relevance in the context of high-fidelity computational physics. The core of the presentation will be on the development of a physical and computational framework towards high-fidelity simulation of icing and frosting. This framework consists of a suit of physical and analytical models from sub-micro scale of the nucleation to the macro-scale of dendritic crystal growth and frost aggregation along with a novel asynchronous process to capture the interactions therein. The ability to characterize the physics of freezing and the degree of details for the physical insights give rise to mitigation concepts that would not be developed otherwise. Towards the end, a synopsis of other capabilities, particularly pertinent to phase change heat transfer will be presented as well. These examples are the precursors to a grander vision toward transforming the paradigm for computational physics from “analysis tools” to “discovery channels”. In this paradigm, computational models will serve as the primary vehicle for providing in-depth physical insight into complex multiphysics of problems across different disciplines and will offer rigorous approach towards next-generation concept exploration and architecture refinement through physics-based innovations.
