WebbAB - In the present study, a new computational methodology is explored to compute the acoustic field of drone propellers using noise source modeling with the lattice Boltzmann method. A simple mathematical model of steady loading noise for predicting the blade passing frequency (BPF) tone and harmonics at low frequencies (100–1000 Hz) is … WebbWe present the development of a non-reflecting boundary condition, based on the Local One-Dimensional Inviscid (LODI) approach, for Lattice Boltzmann Models working with multi-speed stencils. We test and evaluate the LODI implementation with numerical benchmarks, showing significant accuracy gains with respect to the results produced by …
WebbLattice Boltzmann methods, on the other hand, utilize fictitious or fictive particles on a much smaller scale. This allows for discretization over a defined lattice and the application of parallel processing for solutions of flow propagation and internal collisions. This structure allows for variation of fluid parameters between nodes of the ... WebbThe simulating methods can be summarized into two main categories in terms of fluid phase separation methods: (1) solving the Naiver–Stokes (NS) equations with a Young–Laplace equation and generating an interface using the Volume of Fluid (VOF) or Level-Set (LS) on the level of control volume [40,41,42,43,44]; (2) solving the Lattice …
