CONSTRUCTAL DESIGN OF A VORTEX TUBE FOR SEVERAL INLET STAGNATION PRESSURES

Revista de Engenharia Térmica, 2012
The present paper shows a numerical study concerned with the geometrical optimization of a vortex tube device by means of Constructal Design for several inlet stagnation pressures. In the present study, it is evaluated a vortex tube with two-dimensional axisymmetric computational domain with dry air as the working fluid.

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 ...
