Open Jet Testing for Buoyant and Hybrid Buoyant Aerial Vehicles

Open jet testing is a valuable testing technique which provides the desired results with reasonable accuracy. It has been used in past for the airships and now has recently been applied for the hybrid ones, having more non-buoyant force coming from the wings, empennage and the fuselage. In the present review work, an effort has been done to review the challenges involved in open jet testing. In...

Shelf Impact on Buoyant Coastal Current Instabilities

The impact of shelf slope on the linear stability of buoyant coastal currents and on the nonlinear formation of coastal meanders and eddies is investigated. The authors consider a simplified two-layer stratification in cylindrical geometry where a buoyant surface current flows along the coast above a denser water, with a flat bottom or steep shelves. Simulations were performed using the Nucleus...

ALAQS- CFD Comparison of Buoyant Free and Wall Turbulent Jets

This report investigates the effects of a solid boundary on the flow properties of a buoyant jet. A comparison was made with the results of a previous ALAQS report on an unbounded jet to highlight the difference jet behaviours. It is believed that the inclusion of the wall represents a further step towards a better understanding of the source dynamics behind an airplane jet engine during the ta...
