Numerical study on performances of shell-side in trefoil-hole and quatrefoil-hole baffle heat exchangers
TL;DR: In this paper, the influence of opening height on the shell-side performances of trefoil perforated plate baffle heat exchanger with equilateral triangle tube layout and quatrefoil-hole baffle with square tube arrangement has been studied numerically.

Investigations on Blade Tip Tilting for Hawt Rotor Blades Using CFD
TL;DR: In this article, the effects of tip tilting on power production of horizontal-axis wind turbines by using Computational Fluid Dynamics (CFD) were studied. But the main purpose of this paper is to study the aerodynamic effects of blade tip tilts on power generation of horizontal axis wind turbines, and the results are shown in terms of power generation at different wind speeds and the pressure distribution at different sections of the blade.

Reynolds‐stress modelling of M = 2.25 shock‐wave/turbulent boundary‐layer interaction
TL;DR: In this paper, the authors presented a detailed assessment of the turbulence closures by comparison with both mean-flow and turbulent experimental quantities, and provided a critical evaluation of full Reynolds-stresses models for separated supersonic compression ramp.
Numerical simulation of pressure oscillations in large Francis turbines at partial and full load operating conditions and their effects on the runner structural behaviour and fatigue life
TL;DR: In this article, numerical simulations of the instationary flow, based on hybrid turbulence models, and with numerical structural analysis were used to investigate the effect of turbine fatigue life on the turbine fatigue.

Joseph G. Marvin,George Huang +1 more
TL;DR: In this paper, the authors review progress in the development of the hierarchy of turbulence models for Reynolds-averaged Navier-Stokes codes used in aerodynamic applications and make recommendations for a mid-course correction involving close coordination between modelers, CFD developers and application engineers.

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.
