Active aerodynamic drag reduction on morphable cylinders

Pedro Miguel Nunes Pereira de Almeida Reis, Mark Andrew Guttag

We study a mechanism for active aerodynamic drag reduction on morphable grooved cylinders, whose topography can be modified pneumatically. Our design is inspired by the morphology of the Saguaro cactus (Carnegiea gigantea), which possesses an array of axia ...

Comparing Direct and Indirect Thrust Measurements from Passively Fed and Highly Ionic Electrospray Thrusters

Herbert Shea, Simon Dandavino, Daniel George Courtney

Highly ionic beams of several hundred microampere per squared centimeter have been measured from porous glass ionic liquid electrospray sources fabricated using a conventional mill. The thrust output from three prototype devices, two emitting the ionic liq ...

Environmental impact assessment of lignocellulosic lactic acid production: Integrated with existing sugar mills

Pavel Vaskan

Lactic acid (LA) is considered for the diversification and value addition to sugar industry in South Africa, through a bioconversion of sugarcane bagasse and leaves. A bioconversion process was modeled in Aspen Plus (R) V8.6 and its environmental impacts w ...

Sudden expansions in circular microchannels: flow dynamics and pressure drop

John Richard Thome, Navid Borhani, Sepideh Khodaparast

Micro particle shadow velocimetry is used to study the flow of water through microcircular sudden expansions of ratios e = 1.51 and e = 1.96 for inlet Reynolds numbers Re (d) < 120. Such flows give rise to annular vortices, trapped downstream of the expans ...
