Closed-loop separation control over a sharp edge ramp using Genetic Programming [PDF]

open access: yes, 2015
We experimentally perform open and closed-loop control of a separating turbulent boundary layer downstream from a sharp edge ramp. The turbulent boundary layer just above the separation point has a Reynolds number $Re_{\theta}\approx 3\,500$ based on ...

Non-similar solutions for unsteady flow over a yawed cylinder with non-uniform mass transfer through a slot

open access: yesAin Shams Engineering Journal, 2014
Non-similar solutions are found numerically to a system of coupled non-linear partial differential equations indicating, unsteady laminar water boundary layer flow over yawed cylinder using implicit finite difference scheme along with Quasi-linearization

CFD Simulation of Flow in an Abrasive Water Suspension Jet: The Effect of Inlet Operating Pressure and Volume Fraction on Skin Friction and Exit Kinetic Energy

open access: yesAdvances in Mechanical Engineering, 2012
Abrasive particles in the suspension mixture in an abrasive water suspension jet (AWSJ) machining causes acute skin friction effect thereby effectively changing the jet diameter due to wear, which in turn influences jet exit kinetic energy.

Nonlinear input/output analysis: application to boundary layer transition [PDF]

open access: yes, 2020
We extend linear input/output (resolvent) analysis to take into account nonlinear triadic interactions by considering a finite number of harmonics in the frequency domain using the harmonic balance method.

Roughness effects in turbulent forced convection [PDF]

open access: yes, 2018
We conducted direct numerical simulations (DNSs) of turbulent flow over three-dimensional sinusoidal roughness in a channel. A passive scalar is present in the flow with Prandtl number $Pr=0.7$, to study heat transfer by forced convection over this rough

Quantitative assessment of friction perception for fingertip touching with different roughness surface

open access: yesBiosurface and Biotribology, 2015
There are many mechanical stimulation receptors and sensory nerve endings in human skin, which are the important tools in tactile perception. It is a complex process for human to perceive objects and friction relative motion plays an important role ...
