Aerodynamic Drag Analysis of Superpressure and Zero Pressure Balloons using Large Eddy Simulations (LES) [PDF]
Journal of Applied Fluid MechanicsStratospheric balloons are an essential part of the scientific research community. In previous stratospheric balloon models used for trajectory prediction and station-keeping, the aerodynamic drag has usually been modeled as similar to that of a sphere ...

Continuous Eddy Simulation (CES) of Transonic Shock-Induced Flow Separation
Applied SciencesReynolds-averaged Navier–Stokes (RANS), large eddy simulation (LES), and hybrid RANS-LES, first of all wall-modeled LES (WMLES) and detached eddy simulation (DES) methods, are regularly applied for wall-bounded turbulent flow simulations.

Large Eddy simulations of the ceiling jet induced by the impingement of a turbulent air plume [PDF]
, 2016 In this paper, a sensitivity study is performed with FireFOAM 2.2.x for a hot air jet plume impinging onto a flat horizontal ceiling. The plume evolution and the induced ceiling flow are considered. The influence of the level of turbulence imposed at the

Filtered actuator disks: Theory and application to wind turbine models in large eddy simulation [PDF]
Wind Energy, 2019 The actuator disk model (ADM) continues to be a popular wind turbine representation in large eddy simulations (LES) of large wind farms. Computational restrictions typically limit the number of grid points across the rotor of each actuator disk and ...
