OpenFOAM computational fluid dynamics simulations of thermal wind generation in mountain/valley configurations
(2021)
Text en actes de congrés
Accés obertThermal winds appear in mountainous areas and valleys due to temperature gradients caused by the buoyancy effects associated with the diurnal heating-cooling cycle of the lower atmosphere. These winds develop over complex ... -
OpenFOAM numerical analysis of the diurnal cycle of thermally-driven winds on Mars
(2023)
Text en actes de congrés
Accés obertThe study of Martian winds holds significant scientific interest and potential practical applications. For instance, understanding the dynamics and behaviour of Martian winds is crucial in order to properly evaluate and ... -
Perspectives on OpenFOAM numerical simulations of slope winds in Mars
(Budapest University of Technology and Economics, 2022)
Comunicació de congrés
Accés obertPlanetary boundary layer phenomena, such as slope winds and nocturnal low-level jets, are frequent on Mars, e.g., whenever diurnal surface temperature variations are significant, and large-scale winds are weak. In particular, ... -

Sensitivity analysis of maximum circulation of wake vortex encountered by en-route aircraft
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-07-16)
Article
Accés obertWake vortex encounters (WVE) can pose significant hazard for en-route aircraft. We studied the sensitivity of wake vortex (WV) circulation and decay to aircraft mass, altitude, velocity, density, time of catastrophic wake ... -
Simulations of wind formation in idealised mountain–valley systems using OpenFOAM
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-01-11)
Article
Accés obertAn OpenFOAM computational fluid dynamics model setup is proposed for simulating thermally driven winds in mountain–valley systems. As a first step, the choice of Reynolds Averaged Navier–Stokes k-e turbulence model is ... -
