Effect of Freestream Turbulence on Airfoil Limit-Cycle Oscillations at Transitional Reynolds Numbers
TL;DR: In this article, the effect of freestream turbulence on small-amplitude limit-cycle oscillations of an airfoil at transitional Reynolds numbers was investigated using a one-degree-of-freedom aeroelastic model coupled with the National Research Council Canada in-house computational fluid dynamics code INSflow.
Journal ArticleDOI
A review of pressure strain correlation modeling for Reynolds stress models
TL;DR: Most investigations of turbulent flows in academic studies and industrial applications use turbulence models as discussed by the authors, and out of the different turbulence modeling approaches Reynolds stress models have the highest performance in terms of stability.

Large-Eddy Simulation Studies of Bypass Transition
Zhiyin Yang,Peter R. Voke +1 more
TL;DR: In this paper, a large-eddy simulation has been performed of a boundary layer undergoing transition to turbulence owing to the presence of free-stream turbulence, and the results of numerical experiments indicate the roles of the three perpendicular components of free stream turbulence intensity, and of pressure fluctuations, in provoking bypass transition.

Numerical simulation of three-dimensional turbulent separated and reattaching flows using a modified turbulence model
Tsarng Sheng Cheng,W.J. Yang +1 more
TL;DR: In this article, a modified version of k-e model is proposed through modification of the damping function of eddy viscosity that incorporates the effect of wall proximity in the near the wall region and the effects of non-equilibrium away from the wall together with the simple model functions in the e equation.
Journal ArticleDOI
An Implicitly Consistent Formulation of a Dual-Mesh Hybrid LES/RANS Method
TL;DR: Xiao et al. as discussed by the authors proposed a consistent dual-mesh hybrid LES/RANS framework for turbulence modeling to better exploit the advantage of more advanced RANS turbulence models, where the turbulent stresses in the filtered equations in under-resolved regions are directly corrected based on the Reynolds stresses provided by the RANS simulation.

The prediction of laminarization with a two-equation model of turbulence
W.P. Jones,Brian Launder +1 more
TL;DR: In this article, the local turbulent viscosity is determined from the solution of transport equations for the turbulence kinetic energy and the energy dissipation rate, and the predicted hydrodynamic and heat-transfer development of the boundary layers is in close agreement with the measured behaviour.

The calculation of low-Reynolds-number phenomena with a two-equation model of turbulence
W.P. Jones,Brian Launder +1 more
TL;DR: In this article, the authors present numerical predictions of various turbulent shear flows in which the structure of the viscous sublayer exerts appreciable influence on the flow, where the turbulence energy and its dissipation rate are calculated by way of transport equations which are solved simultaneously with the conservation equations for the mean flow.

Heat and mass transfer from rotating cones
C. L. Tien,D. T. Campbell +1 more
TL;DR: In this article, heat transfer by convection from isothermal rotating cones is investigated experimentally by measuring the sublimation rate from naphthalene-coated cones and using the analogy between heat and mass transfer.
