In sports facilities, a grandstand is the structure which provides good sight quality and safety evacuation conditions for the spectators. Grandstand plays important functional and formative roles in sports facilities, and especially in large scale stadia. This paper argues the notion of shape grammar and its computer implementation will solve...

We report experimental results on the Lagrangian dynamics of finite-size light particles in turbulence. Using an orthogonal camera setup and 3D particle tracking, we study the velocity and acceleration statistics of rigid light spheres in a water tunnel with nearly homogeneous and isotropic turbulence. The Reynolds number (ReY) is varied from...

In this study, we exploit the ?PIV (microscale particle image velocimetry) analysis to investigate the internal flow field of a dividing droplet in a bifurcating microchannel. Herein, droplets are generated by a flow focusing scheme and sent downstream toward an asymmetric bifurcation. In order to control the proportion of split droplets, we...

In this talk we focus on the velocity fluctuations in highly turbulent Taylor-Couette flow for the case of stable flow (constant rotation) and for decaying flow. Turbulent flows are generally characterized by the range of scales of their fluctuations, and a statistical description of the flow is often done by calculating the correlations of...

We investigate the double diffusive convection between two parallel plates with either no-slip or free-slip boundary conditions. Direct numerical simulations have been conducted systematically for a series of control parameters. Salt fingers can be observed for both boundary conditions and all parameters explored. Compared to the no-slip case,...

In Taylor-Couette flow, the radius ratio ($\eta = r_i/r_o$) is one of the key parameters of the system. For small $\eta$, the asymmetry of the inner and outer boundary layer becomes more important, affecting the general flow structure and boundary layer characteristics. Using high-resolution particle image velocimetry we measure flow profiles...

Compacted bentonite is often planned as an engineered barrier material between host rock and canister in nuclear waste disposal repositories thanks to its favourable swelling characteristics and low permeability. This study deals with the effects of initial dry density and vertical stress on the swelling behaviour of compacted bentonite under...

The gait of humans is often assumed to be the most energy efficient way of walking. Srinivasan and Ruina [18] confirm this hypothesis using a simple model in which the human is a point mass with straight legs that can change in length during a step. Their results show that the inverted pendulum walk is the most energy efficient gait. The...

A new Nano Air Vehicle (NAV) configuration based on a coaxial nano rotor has been studied by ISAE. The coaxial rotor provides the thrust necessary for hovering and low speed translation flight. The major design challenge for rotary-wing NAVs is related to the difficulty of miniaturizing complex mechanisms such as a rotor cyclic pitch swashplate...

Cochlea implants can help deef patients to regain hearing. The implants consist of a microphone, a speech processor and an electrode array implanted in the inner ear in order to directly excite the auditory nervs. Recently, an electrode array has been designed to be implanted without inner ear trauma aiming at combining rest hearing with the...
