Unsteady aerodynamic force prediction on a square cylinder using k−ε turbulence models
TL;DR: In this paper, the authors investigated numerical effects on the computation of turbulent flows over a square cylinder and found that some conventional k−e models may give reasonable predictions when proper numerical parameters are incorporated.

The effect of the low Reynolds number k-e turbulence models on simulation of the enhanced and deteriorated convective heat transfer to the supercritical fluid flows
Mahdi Mohseni,Majid Bazargan +1 more
TL;DR: In this paper, a two dimensional CFD code has been developed and used in this study to examine a number of the low Reynolds number k-e turbulence models, and the results appear to be quite sensitive to the choice of the turbulence model, especially in the deteriorated regime of heat transfer.
Journal ArticleDOI
Macroscopic modeling of turbulent flow over a porous medium
TL;DR: In this article, the authors present a numerical implementation for examining a hybrid domain, involving both a porous region and a clear fluid region, which is not fully understood primarily due to a lack of proper mathematical treatments of different regions and the fluid/porous interface.

Tip-Clearance and Secondary Flows in a Transonic Compressor Rotor
Georges Gerolymos,I. Vallet +1 more
TL;DR: In this paper, the authors investigated the tip-clearance and secondary flows numerically in a transonic compressor rotor by integrating the Favre-Reynolds-averaged Navier-Stokes equations, using the Launder-Sharma near-wall k-∈ turbulence closure.

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.
