Turbulent Kinetic Energy Production in the Vane of a Low-Pressure Linear Turbine Cascade with Incoming Wakes [PDF]
Incompressible large eddy simulation and direct numerical simulation of a low-pressure turbine at Re=5.18×104 and 1.48×105 with discrete incoming wakes are analyzed to identify the turbulent kinetic energy generation mechanism outside of the blade ...

Minimalist turbulent boundary layer model [PDF]
We introduce an elementary model of a turbulent boundary layer over a flat surface, given as a vertical random distribution of spanwise Lamb-Oseen vortex configurations placed over a non-slip boundary condition line. We are able to reproduce several important features of realistic flows, such as the viscous and logarithmic boundary sublayers, and the ...

The effect of wall cooling on a compressible turbulent boundary layer [PDF]
Experimental results are presented for two turbulent boundary-layer experiments conducted at a free-stream Mach number of 4 with wall cooling. The first experiment examines a constant-temperature cold-wall boundary layer subjected to adverse and ...

Logarithmic mean temperature profiles and their connection to plume emissions in turbulent Rayleigh-B\'enard convection [PDF]
Two-dimensional simulations of Rayleigh-B\'enard convection at $Ra = 5\times10^{10}$ show that vertical logarithmic mean temperature profiles can be observed in regions of the boundary layer where thermal plumes are emitted.
