Summary

A CRYOGENIC ENVIRONMENT PROVIDES A MEANS OF OBTAINING, SIMULTANEOUSLY, LARGE INCREASES IN BOTH THE REYNOLDS NUMBER AND THE GRASSHOF NUMBER ; IT PROVIDES AN EXCELLENT TOOL FOR FORCED, NATURAL AND COMBINED CONVECTIVE HEAT TRANSFER RESEARCH (AERODYNAMIC RESEARCH). IN ADDITION, THE CRYOGENIC ENVIRONMENT VIRTUALLY ELIMINATES THE INFLUENCE OF RADIATIVE HEAT TRANSFER. THE CRYOGENIC FACILITY USES GASEOUS NITROGEN AS THE WORKING FLUID AND IS CAPABLE OF OPERATING AT ANY TEMPERATURE BETWEEN 80 AND 300 K AND AT VELOCITIES BETWEEN 0 AND 8 M/S. THE TUNNEL HAS A RECTANGULAR TEST SECTION WHICH IS 1.2 M IN HEIGHT BY 0.6 M. A HEAT TRANSFER STUDY FROM A VERTICAL RIGHT-CIRCULAR CYLINDER, A MODEL OF THE 10 MW SOLAR-THERMAL ELECTRIC PLANT IN BARSTOW, CALIFORNIA, IS IN PROGRESS. J. V.
