Computing in Science & Engineering Physics, medicine, astronomy — these and other hard sciences share a common need for efficient algorithms, system software, and computer architecture to address large computational problems. And yet, useful advances in computational techniques that could benefit many researchers are rarely shared. To meet that need, Computing in Science & Engineering (CiSE) presents scientific and computational contributions in a clear and accessible format.

  • Touching Data: Enhancing Visual Exploration of Flow Data with Haptics
    on July 13, 2018 at 10:12 am

    Using the example of interactive exploration of the beating heart, the authors demonstrate how data exploration and analysis can be further improved by adding haptics. This combination of sensory information input leads to the notion of visuo-haptic visualization. […]

  • Advanced Computational Simulations of Surface Impingement of a Train of Ethanol Drops: A Pathway to Developing Spray-Wall Interaction Submodels
    on July 12, 2018 at 10:32 pm

    The authors present a computational study of drop-train impingement on a smooth, initially dry surface, with the aim of providing a high-quality dataset to develop reliable spray-wall interaction submodels for engine simulations. Such submodels require information at micron scales, which is unfeasible to obtain experimentally under high-pressure engine conditions. However, supercomputing and high-resolution simulations can resolve thin liquid structures and their breakup, yielding accurate datasets for liquid splashing and film deposition. The current study employs an MPI-parallel multiphase flow solver to simulate surface impingement of a train of ethanol drops. Comparing its results to the experiments, the solvers capability in accurately capturing the sharp splashing threshold and splashed mass ratio was demonstrated. Through a computational technique that tags individual drops, further insight into the splashing dynamics postimpingement was gained, which could be used to formulate more sophisticated spray-wall interaction submodels.
