    Grant-in-Aid for Scientific Research(C)  Principal Investigator  20K04236 

    This research aimed to analyze hydrodynamic lubrication using the particle-based method, which is considered to be able to numerically analyze violent flow with large deformations of the gas-liquid interface. A method for calculating surface tension was proposed and a calculation code was developed to verify its action by comparison with theory and conventional experiments. Hydrodynamic lubrication analysis was carried out using the code, and it was confirmed that the results were the same as those obtained by conventional experimental and numerical analysis. Furthermore, we analyzed the case where the inlet side oil film was not full-filled with oil, which was difficult to analyze with conventional methods, and confirmed that the shape of the inlet oil film could affect the pressure profile. The flow field in the oil film, which is difficult to observe experimentally, was visualized.

  • Interfacial Slip on Sheared Liquid Bridge

    Project Period (FY)： 2015/04  -  2019/03  Investigator(s): Tanaka Kentaro

    Grant-in-Aid for Scientific Research(C)  Principal Investigator  15K05757 

    To reveal effects of an interfacial slip on frictional behavior of a sheared liquid meniscus bridge, experimental apparatus which can detect the interfacial wet precisely is developed. And, to analyze a mechanism of the interfacial slip, numerical simulator which can trace fluid dynamics with large deformation of liquid-air interface is developed.
    The experimental apparatus with an interference fringe method allows precise detection of wet line, and measurement of contact angle of below 1 degree. The numerical simulator by using particle-based method allows simulation of shearing liquid bridge with large deformation.
