| Abstract: Using the boundary perturbation technique together with Eyring's transition-rate-theory model, we can obtain approximately the slip velocity of amorphous fluids inside the wavy-rough microtube. Our calculations show that, once the slip length is set to zero, there is a temperature as well as an activation energy-dependent slip velocity (up to second order) near the wall. This nonzero velocity near the boundary of the microtube is proportional to the small amplitude of wavy-roughness, the curvature of the tube (inner) surface, the applied forcing, the orientation and the referenced shear rate, which is strongly temperature dependent once the activation energy is fixed. |

| Title: NUMERICAL ANALYSIS OF THE DRAG FORCES ACTING ON THE STATIONARY IMPENETRABLE NANO-TUBE |

| Abstract: The motion of nano-particles is important in many technical areas, for example super hydrophobic spray for coating materials, nano-capsules for detecting cancer, and additive nano-particles in oil and fuel for automotive engines. In this paper computations are performed to determine the steady flow forces acting on the stationary nano-tube for Reynolds numbers in the range of 0.1<Re<40 and 0.01<Kn<0.1 with the slip boundary condition. A single dimensionless parameter, the so-called slip number (Tr), is defined to account for the slip at the cylinder's boundary. Increasing slip causes to delay of flow separation around the nano-tube surface. Numerical results confirm that slip variations can not affect on the drag coefficient values at low Reynolds regime. At higher Reynolds number increasing slip causes to drag reduction of flow around the nano tube. |

| Title: SLIPPAGE AND WETTING TRANSITION OF WATER FLOW IN SUPERHYDROPHOBIC MICRO-CHANNEL |

| Abstract: We investigate the slippage effect in a super-hydrophobic micro-channel. The micro-scale grooves are fabricated on the vertical wall to make the super-hydrophobic surfaces, which enable us visualize the flow fields near walls and directly measure the slip length. Velocity profiles are measured using micro-particle image velocimetry (PIV). The velocity profile near the wall shows larger slip length and, if the groove structure is high and wide, the liquid meniscus forms curves into the valley so that the wavy flow is created after the grooves. Also depending on the ratio of pitch to width of the groove structure, the water meniscus status can be either sustained between the valleys or collapsed to be wet. This Cassie to Wenzel transition is observed in the micro-channel. And we investigate the effects of grooves shape and the flow rate on the wetting transition. |
