Test Case

Brief Description of the Study Test Case

The experiments used in this UFR are those of George et al. [3] which were conducted in 1974 at the Factory Mutual Research Corporation and were subsequently repeated by Shabbir & George [33] at the University of Buffalo.

• Heated air is discharged through a circular orifice into ambient air that is at rest. • The plume source temperature is 300°C and the ambient air is 29°C. • The source has diameter, D = 6.35 cm. • The hot air is discharged at a velocity of U0 = 67 cm/s with a approximately a top-hat profile. • Temperature and velocity fluctuations at the inlet are less than 0.1%. • George et al. [3] present experimentally measured profiles of both mean and fluctuating components of the temperature and axial velocity in the self-similar region at x/D = 8, 12 and 16 above the source.
