Modeling of Flow Transition Using an Intermittency Transport Equation
Y. B. Suzen,P. G. Huang +1 more
TL;DR: In this article, a new transport equation for intermittency factor is proposed to model transitional flows by modifying the eddy viscosity, mu(sub t), obtainable from a turbulence model.

Combined simulation of airflow, radiation and moisture transport for heat release from a human body
TL;DR: In this article, a combined numerical simulation method of airflow, thermal radiation and moisture transport for predicting heat release from a human body was described, and a human thermo-physiological model was also included to examine the sensible and latent heat transfer from the human body.
Journal ArticleDOI
Progress in the generalization of wall-function treatments
TL;DR: The aim is to enable the effective “resistance” of the viscous sublayer to the transport of heat and momentum to be packaged in the form of a “wall function”, thus enabling CFD predictions of convective heat transfer to be made without incurring the cost of the very fine near-wall grid that would otherwise have to be adopted.

Experiments on turbulent natural convection in an enclosed tall cavity
P.L Betts,I.H Bokhari +1 more
TL;DR: In this paper, the authors investigated the natural convection of air in a tall differentially heated rectangular cavity (2.18 m high by 0.076 m wide by0.52 m in depth) with temperature differentials between the vertical plates of 19.6°C and 39.9°C.

Modeling Rotating and Swirling Turbulent Flows: A Perpetual Challenge
TL;DR: In this paper, the second-moment closure and two eddy-viscosity models were evaluated with three versions of thesecondmoments closure and showed that the secondmoment models are superior, especially when the equations are integrated up to 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.
