Application of the David Taylor Navier-Stokes (DTNS) Code in Non- Inertial Reference Frames

Abstract

This report describes the extension of the DTNS computer codes to treat non-inertial reference frames. Both laminar and turbulent flow calculations are performed. Additionally, the applicability of currently available turbulence models in non-inertial reference frames is investigated. It is found that the typical algebraic eddy viscosity and two-equation k - e models used in inertial reference frames are not capable of predicting the effects of rotation. Two-equation k - e and algebraic Reynolds stress models that have been modified, to account for rotation, perform somewhat better but still have problem areas and it is not yet known to what extent they can be used with confidence for complex flow fields. Navier-Stokes Equations, rotation, turbulence modelling.
