Effects of mean flow skew on turbulent shear layers. Part I. Numerical investigation
Vedant Kumar, Dipendra Gupta, Gregory Paul Bewley +1
Skewed turbulent shear layers, formed by the interaction between two non-aligned turbulent boundary layers, are investigated using high-fidelity large eddy simulations in a tempora…
Effects of mean flow skew on turbulent shear layers. Part II. Experimental investigation
Dipendra Gupta, Vedant Kumar, Johan Larsson +1
Planar turbulent mixing layers, formed by the interactions of two parallel streams with different velocities, have been studied far more than three dimensional (3D) turbulent mixin…
Experimental Evidence for Longitudinal Scaling Exponent Saturation in Shear Turbulence
Dipendra Gupta, Gregory P. Bewley
The asymptotic behavior of velocity statistics in the tails of distributions and at high Reynolds numbers remains unresolved in turbulence. To investigate this behavior we measured…
Experimental investigation of intermediate-dissipation range energy spectra in shear turbulence
Dipendra Gupta, Edmund T. Liu, Gregory P. Bewley
The shape of the turbulent energy spectrum in the dissipation range, where viscous effects dominate, remains an open question despite decades of work. We report an experimental inv…
