“…A Laser-Doppler anemometric study of the turbulence characteristics of plasma jets has been initiated in this laboratory which will hopefully clarify the picture. This information is all the more needed in view of the evidence that turbulence exerts a strong influence on particulate heat transfer (Brandon and Grizzle, 1971). In this connection, the reader is referred to a recent paper by Waldie (1972b) in which he presents a thorough review of the experimental evidence so far published in the field of heat and mass transfer to particles in plasmas.…”

Axial and radial profiles of temperature and velocity of an argon plasma jet in open air, were measured by a calorimetrie probe, at temperatures up to 11 600 0 K and velocities up to 410 mIs. The radial profiles were shown to be Gaussian.Velocities and decelerations of elose-sized microspheres (30 -140~m dia) in the plasma jet were measured by a high-speed streak camera. A maximum partiele deceleration of 8 000 g was observed.Experimental drag coefficients were found to be about 30% greater than standard curve values. This increase was in accord with the computer predictions of the value of the Basset history term in the full equation of motion.

Wall mass transfer rates of dissolved oxygen have been measured in a vertical pipe, 5 cm. I.D., carrying aqueous slurries of 5, 10, and 15 vol%, 60–100 and 30–50 mesh sands at velocities in the range 1.2 to 3.35 m/s. The results show increases of up to 100% over those found with water, with the effect of the solids increasing with decreasing particle size and increasing with increasing concentration. The jD factors decreased linearly with increasing Res, unlike the previous results with horizontal pipes where maxima were found relating to vertical concentration gradients.

Heat transfer to flowing gas–solid mixtures in pipes is required in many applications including chemical processing, pneumatic transport, and nuclear reactors but no well-verified method for predicting heat transfer is available. A new correlation is presented, which has been validated with a wide range of data that includes a variety of particles (minerals, metals) in several gases. Particle diameters range from 13 to 1130 µm, pipe diameters 5.1 to 77 mm, and the solids loading ratio of 0–520. Flow orientations include horizontal, vertical up, and vertical down. The new correlation has a mean absolute deviation (MAD) of 18.9% with 630 data points from 20 studies. The same data were also compared with six published correlations. Their MAD ranged from 35% to 57%. Hence, the new correlation is likely to help in more accurate design.
