On the hydrodynamics and heat convection of an impinging external flow upon a cylinder with transpiration and embedded in a porous medium [PDF]
, 2017 This paper extends the existing studies of heat convection by an external flow impinging upon a flat porous insert to that on a circular cylinder inside a porous medium.

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 ...

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
