Steady flow over triangular extended solid attached to square cylinder – A method to reduce drag
Ain Shams Engineering Journal, 2015 Numerical analysis of two dimensional steady flows over a triangular extended solid (thorn) attached to square cylinder positioned at front stagnation point and at rear stagnation point separately is reported at low Reynolds number (Re = 40).

Simulation of flight test conditions in the Langley pilot transonic cryogenic tunnel [PDF]
The theory and advantages of the cryogenic tunnel concept are briefly reviewed. The unique ability to vary temperature independently of pressure and Mach number allows, in addition to large reductions in model loads and tunnel power, the independent ...

On the horseshoe drag of a low-mass planet. II Migration in adiabatic disks
, 2009 We evaluate the horseshoe drag exerted on a low-mass planet embedded in a gaseous disk, assuming the disk's flow in the coorbital region to be adiabatic.

CONTROL OF REYNOLDS NUMBER IN A HIGH SPEED WIND TUNNEL. doi: 10.5028/jatm.2009.01016977
Journal of Aerospace Technology and Management, 2011 A conceptual control model for the Reynolds number test based on isentropic relations was established for the supersonic wind tunnel. Comparison of the system response of the model simulation and the actual wind tunnel test data was made to design the ...

Some flow phenomena in a constant area duct with a Borda type inlet including the critical region [PDF]
Mass limiting flow characteristics for a 55 L/D tube with a Borda type inlet were assessed over large ranges of temperature and pressure, using fluid nitrogen. Under certain conditions, separation and pressure drop at the inlet was sufficiently strong to

The pressure confined wind of the massive and compact superstar cluster M82-A1
, 2007 The observed parameters of the young superstar cluster M82-A1 and its associated compact HII region are here shown to indicate a low heating efficiency or immediate loss, through radiative cooling, of a large fraction of the energy inserted by stellar ...

Recent stagnation period and unprecedented deoxygenation in the Baltic Sea: causes and consequences
Frontiers in Earth ScienceThe properties of the Baltic Sea deep waters are strongly influenced by the alternation between Major Baltic Inflows (MBIs) and the stagnation periods separating them.
