A near wall k—ε formulation for high Prandtl number heat transfer
TL;DR: In this paper, an improved form of the so-called "near-wall" k-e turbulence model is proposed, where damping functions accounting for viscous effects at low Reynolds numbers are modified to yield a turbulent viscosity that properly predicts heat transfer rates over a wide range of Prandtl numbers.

Time-accurate Numerical Simulations of Swirling Flow with Rotor-stator Interaction
Ardalan Javadi,Håkan Nilsson +1 more
TL;DR: In this article, a series of numerical simulations are undertaken to study a highly swirling turbulent flow generated by rotor-stator interaction in a swirl generator, and the applicability of different turbulence models in swirling flow with a high level of unsteadiness and a significant production and dissipation of turbulence in the flow away from the wall.

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.
