Rim driven thruster consists of a fan actuated into a rotational motion by a mechanism located at its outer radius, rather than by a centerline shaft as seen in conventional fan designs. Such configuration eliminates a need for a centerline hub containing driving mechanism, allowing for an undisturbed core flow of ...

Webby Oleg Goushcha, Vahid Azadeh Ranjbar, Yiannis Andreopoulos. The lack of understanding and the complexity of vortex induced vibration (VIV) physics combined with a diverse range of applications have motivated a number of studies in this field. While large vibration amplitude due to VIV in general should be avoided in the design of engineering ... WebOleg Goushcha (Manhattan College) Yiannis Andreopoulos (The City College of New York) Pulsatile flows are of interest because for certain range of characteristic non-dimensional parameters, they display laminar and turbulent behavior at different times of the pulsating cycle. Addressing how turbulence appears, decays and is suppressed is ... how to travel from boston to salem
