Multigrid Computation of Incompressible Flows Using Two-Equation Turbulence Models: Part I—Numerical Method
TL;DR: In this article, a highly efficient numerical approach based on multigrid and preconditioning methods is developed for modeling 3-D incompressible turbulent flows, and all the acceleration techniques originally developed for N-S equations are also used for the turbulence model equations.
Journal ArticleDOI
Two-equation modeling of turbulent rotating flows
TL;DR: Howard and Bordynuik as discussed by the authors examined the effect of the Coriolis acceleration on turbulence in the framework of two-equation eddy-viscosity models and derived results on the physical consistency of such turbulence models from a dynamical-system approach to situations of time-evolving homogeneous turbulence in a rotating frame.
Journal ArticleDOI
Simulation of overflow nappe impingement jets
TL;DR: In this paper, the authors used a two-fluid model, turbulence models and mesh-size analysis to identify the level of reliability of computed parameters, validation of air entrainment and velocity along free falling jets, thickness and break-up of jets, and pressures on the bottom of the plunge pool.
Certificate of originality
TL;DR: The results reveal that the BNT thin films can crystallize well into a single phase of bismuth layered perovskite structure at 650°C and 700°C, however, a higher annealing temperature results in larger grains and better properties, which should be employed in various sensor applications.

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.
