An efficient modeling framework for wall heat flux prediction in rocket combustion chambers using non adiabatic flamelets and wall-functions
TL;DR: In this paper, an efficient numerical framework for the prediction of wall heat loads in Liquid Rocket Engine combustion chambers is presented. The proposed framework is based on a new version of the non-adiabatic flamelet model and on wall functions for turbulent boundary layer modeling.

Accounting for Melt Flow Pattern and Solid Fraction Evolution in DC Casting of Al-Cu Alloy Using v 2 {-}f Turbulence Model
TL;DR: In this article, the authors employed a low-Re $$ v^{2}{-}f$$ turbulence model and a dual-zone solidification flow model to predict the melt flow pattern, turbulence level, sump depth, transition zone thickness, and mushy zone thickness in the direct chill casting of Al-Cu alloy.

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.
