  • Prediction of ship propulsion resistance with machine learning

    The Other Research Programs  

    Project Year： 2017.4

    　More detail

    Experimental and numerical data for ship towing tank test are used as the test data of machine learning, and the innovative prediction system for the propulsion resistance of new ship model is developed with low computational cost.

  • Numerical simulation of oil spill due to tsunami and development of the method for reducing the disaster impact

    Cooperative Research  

    Project Year：

    　More detail

    A numerical simulation for predicting the impact of oil spill disaster triggered by large tsunami at chemical industrial park is carried out, and a method for reducing the impact is developed.

  • Study on drag reduction effect of hydrogel ship painting with meso-scale model

    Grant-in-Aid for Scientific Research  

    Project Year：

    　More detail

    To clarify the drag reduction effect of hydrogel painting, a meso-scale model for connecting the macro scale fluid motion with the micro scale structure of painting polymer is developed, and the relation between vortex motion and turbulent dynamics is investigated.
