An experimental investigation of combined convective heat transfer from a smooth, isothermal vertical cylinder to a surrounding gas medium is described. The study was motivated by the desire to predict the convective heat loss from the 10-MWe pilot plant solar receiver in Barstow, California. Hence emphasis is placed on the supercritical (Reynolds number Re greater than 105 , turbulent (Rayleigh number RaL greater than 109 ) regime. The influences of the Reynolds number, the Rayleigh number, the Richardson number, and Tw /T∞ —the ratio of the surface temperature, Tw to the ambient air temperature T∞ —are deduced. Large ranges of these dimensionless parameters are covered with a single model by using a variable ambient temperature, cryogenic wind tunnel over the temperature range 80 K ≤ T∞ ≤ 300 K. The cryogenic facility also enables the simultaneous generation of large Rayleigh numbers and large Reynolds numbers.
