51st Fluid Dynamics Conference / the 37th Aerospace Numerical Simulation Symposium (July 1-3, 2019. International Conference Center, Waseda University), Shinjuku-ku, Tokyo, Japan
Research on prediction technology of water spray generated from aircraft tires is going on in JAXA. As a prediction tool, a numerical code using the explicit MPS (Moving Particle Simulation) method, which is one of the particle methods, is being developed to simulate the water spray. As a benchmark problem, the water spray test conducted by NASA was simulated under a simplified condition. It was found that the angle of side spray observed behind the tire is consistent with the experimental data when the deformation of the tire due to load is taken into account, whereas the angle was underestimated when the deformation was ignored. Experimental efforts to obtain in-house data are also being made to validate the simulation. A laboratory model has been fabricated to establish the technology to measure the water behavior, and a test using actual tire is also planned in the near future.
