DRA REDUCTION IN TURBULENT FLOWS OVER MICROPATTRNED SUPERHYDROPHOBIC SURFACES
DRAG REDUCTION IN TURBULENT MICROPATTERNED SUPERHYDROPHOBIC SURFACES
2014/10/23
Periodic, micropatterned superhydrophobic surfaces, previously noted for their ability to provide drag reduction in the laminar flow regime, have been demonstrated capable of reducing drag in the turb...
Particle drift in turbulent flows: the influence of local structure and inhomogeneity
turbulent structures particle dispersion drift PDF approach
2012/5/31
The way particles interact with turbulent structures, particularly in regions of high vorticity and strain rate, has been investigated in simulations of homogeneous turbulence and in simple flows whic...

Abstract: We show that in turbulent scalar mixing the advection is strongly suppressed with respect to its Gaussian estimate. This effect is particularly important in the small scales. Results are giv...
The Prediction of the Wall Bounded Turbulent Flows Using the Code PASSABLE

2009/10/15
Turbulent flows for flat plate and circular pipes were solved using the two equation k-" model and the algebraic stress model (ASM). The computations were carried out using the parabolic solver PASSAB...
