View Video Presentation: https://doi.org/10.2514/6.2022-3522.vid Reynolds-averaged Navier-Stokes (RANS) solutions obtained with scFLOW, a polyhedral finite-volume solver, are presented for the fourth AIAA CFD High-Lift Prediction Workshop (HLPW4). We use two types of numerical meshes: a provided mesh and a polyhedral mesh generated with scFLOW. Thi...
Article
Numerical simulations of aerosol motion induced by sneezing and exhalation were carried out by CFD (Computational Fluid Dynamics) with modeled particles. For sneezing analysis, with and without covering by an elbow and wearing a face mask were modeled to clarify the effect of how to prevent scattering. Aerosol scattering from a talking passenger in...

RANS solutions obtained with scFLOW, a polyhedral finite-volume solver developed atSoftware CRADLE, are presented for three-dimensional benchmark problems in NASA’sturbulence model resource website. Grid convergence study is performed, and the resultsare presented and compared with other codes (NASA’s FUN3D, CFL3D, USM3D) for twobenchmark configura...
Article
Karman vortex sheets from a two dimensional circular cylinder at low Reynolds number are calculated using node-centered Finite Volume Method and unstructured mesh. In order to prepare for a coupling analysis between flow and structure oscillation, dependence of mesh density for frequency of vortex shedding are investigated in this paper. The result...
Article
Acoustic waves radiated by the interaction of a single vortex colliding head on with a body in a uniform flow are simulated numerically. The two-dimensional, unsteady, compressible Navier-Stokes equations are solved by a finite difference method. The results show that the dipole sounds are generated basically three times according to two times osci...

Full-text available
Mesoscopic phase transitions and the critical behavior of nanostructured materials are summarized for three-dimensional systems (1) of simple particles starting from grains of fcc or hcp and two-dimensional spin-particle systems (2), and generalized q-state (q=3,4) Potts-spin systems (3), interacting magnetoelastically. The interactions are taken i...
Article
Direct Numerical Simulation results of aeolian tones generated by a two-dimensional obstacle (square cylinder and NACA0012 airfoil) in a uniform flow are pre-sented and the generation and propagation mechanisms of the sound are discussed. The two-dimensional unsteady compressible Navier-Stokes equations are solved by a highly-accurate finite differ...
