Numerical Study of Turbulent Flow around a Generic Airship at High Angle of Attack

This article presents a numerical study of turbulent flow around a generic three-dimensional prolate spheroid with a 20◦ angle of attack. The Reynolds number we use is a moderate one Re = 4 × 104. In this work we compare three different turbulence models : the RANS k − ε, the LES Smagorinsky and the VMS-LES. The numerical code makes use of a mixed FE/FV formulation based on tetrahedra. A Roe’s ...

Turbulent bubbly flow in pipe under gravity and microgravity conditions

High Angle of Attack Aerodynamics

High angle of attack aerodynamics is inherently associated with: • separated flows, and thus nonlinear aerodynamics > one of the key aspects is the interaction of components, and in particular, vortex flows (vortex bursting is also an important effect) • heavily dependent on wind tunnel testing • connected with flight simulation to ensure good handling qualities > this means that large amounts ...

Small angle neutron scattering (SANS) under non-equilibrium conditions

2014 The use of small angle neutron scattering (SANS) for the study of systems under non-equilibrium conditions is illustrated by three types of experiments in the field of polymer research : 2014 the relaxation of a system from an initial non-equilibrium state towards equilibrium, 2014 the cyclic or repetitive installation of a series of non-equilibrium states in a system, 2014 the steady non-...
