Abstract

The prediction of drag force on spheres whose diameters are comparable to or greater than the dimensions of jets to which they are exposed is found to be much more difficult than in the more usual ‘fully immersed’ cases. Experimental results show considerable scatter but prediction guidelines are given in the paper. In Reynolds-number terms all results are considered to be supercritical ones because of the typically very high turbulence intensities in the mixing regions of jets.
