A new method for predicting the vortex induced aerodynamic characteristics of a body of revolution [PDF]

open access: yes, 1995
The problem of mathematically modelling the symmetric vortex pair formed on the lee side of a body of revolution at moderate incidence to the freestream direction is addressed with a view to predicting its aerodynamic characteristics.

A Mathematical Model to Analyze the Static Stability of Hybrid (Aero- Hydrodynamically Supported) Vehicles. [PDF]

open access: yes, 2008
Among the new concepts developed for high speed marine vehicles over the last two decades, the "aerodynamic alleviation" approach consists in using an aerodynamic surface to "alleviate" the weight sustained by the hydrodynamic lift.

In Vivo Aerodynamic Characteristics of the Nijdam Voice Prosthesis [PDF]

open access: yesActa Oto-Laryngologica, 1997
The Nijdam voice prosthesis is an indwelling valveless voice prosthesis for postlaryngectomy voice rehabilitation. The in vitro aerodynamic characteristics are reported to be comparable to that of the low-resistance Groningen voice prosthesis. Owing to the design of the prosthesis the airflow resistance depends on the shaft length of the voice ...
