Imbedded Longitudinal Vortices In Turbulent Boundary Layers

Imbedded Longitudinal Vortices in Turbulent Boundary Layers

Measurements, including all Reynolds stresses and triple products, have been made in three turbulent flows with imbedded longitudinal vortices generated by skewing of the mean flow ('secondary flow of the first kind') (i) flow in an idealized wing-body junction, (ii) an isolated vortex in a two-dimensional boundary layer, and (iii) a vortex pair in a turbulent boundary layer. Selected results are presented: spatial variations of eddy diffusivities and dimensionless modelling parameters are seen to be complicated. (Author).

New Approaches of Geotechnical Engineering: Soil Characterization, Sustainable Materials and Numerical Simulation

The studies presented in this volume cover new approaches of geotechnical engineering introduced by researchers, engineers and scientists to address contemporary issues in geotechnical engineering such as the usage of sustainable materials in soil, soil characterization with new methods, and numerical simulations to predict material properties, etc. Studies were selected from the 6th GeoChina International Conference on Civil & Transportation Infrastructures: From Engineering to Smart & Green Life Cycle Solutions -- Nanchang, China, 2021.
