| Research Abstract |
A grid-free vortex method was developed and applied to turbulent flows in order to validate and improve the scheme. The spatial resolution was successfully improved for high strain regions. The calculation was accelerated by using Graphics processing Units(GPUs). From the results, it was confirmed that the unsteady feature of the turbulent flows and the development were successfully captured. Furthermore, comparisons of the calculated mean velocity and the calculated rms value of the velocity fluctuation with experimental data showed that the method provided an accurate velocity profile.
