Thin-layer approximation and algebraic model for separated turbulent flows
B. Baldwin,H. Lomax +1 more
TL;DR: In this article, an algebraic turbulence model for two-and three-dimensional separated flows is specified that avoids the necessity for finding the edge of the boundary layer, and compared with experiment for an incident shock on a flat plate, separated flow over a compression corner, and transonic flow over an airfoil.

Predictions of Channel and Boundary-Layer Flows with a Low-Reynolds-Number Turbulence Model
TL;DR: In this paper, the Taylor series expansion technique was used to systematically investigate the proper behavior of the turbulent shear stress and the kinetic energy and its rate of dissipation near a solid wall.
Turbulence Modeling Validation, Testing, and Development
TL;DR: In this paper, the authors provide accurate numerical solutions for selected flow fields and to compare and evaluate the performance of selected turbulence models with experimental results, including free shear flows, boundary layer flows, and axisymmetric shockwave/boundary layer interaction.
Proceedings ArticleDOI
Turbulence modeling validation
TL;DR: In this article, the performances of four turbulence models are evaluated against eight selected experimental flow fields, including freeshear flows, an incompressibl e boundary layer, and three complex flows with flow separation.

Wall-modeling in large eddy simulation: Length scales, grid resolution, and accuracy
Soshi Kawai,Johan Larsson +1 more
TL;DR: In this paper, the authors proposed a method that allows for the log-layer mismatch to be removed, thereby yielding accurately predicted skin friction, by considering the behavior of turbulence length scales near a wall.

The Turbulent Boundary Layer
TL;DR: In this article, the authors examined the effect of roughness on boundary layer characteristics and showed that the wall is aerodynamically smooth for a turbulent boundary layer if the roughness elements are so small as to be buried in the laminar sublayer.

Das Aehnlichkeitsgesetz bei Reibungsvorgängen in Flüssigkeiten
TL;DR: In den meisten Interpolationsformeln der Hydraulik, die die Druckvertilung in bewegtem Wasser betreffen, wahlt man als ersten Ansatz die Proportionalitat der Druckhohe as mentioned in this paper.
A Method of Correlating Forced Convection Heat Transfer Data and a Comparison with Fluid Friction
TL;DR: In this article, a general method for the correlation of forced convection heat transfer data is proposed, which consists in plotting, against the Reynolds number, a dimensionless group representing the experimentally measured data from which film heat-transfer coefficients would be calculated, namely, [ (t 1 − t 2 ) Δt m ] (S A), or its equivalent, h cG, multiplied by the two-thirds power of the group, (cμ k).

D. B. Spalding,S. W. Chi +1 more
TL;DR: In this article, the root-meansquare error of the theory of van Driest-II was calculated by using mixing-length theory and semi-empirically.
