Themass transferfrom a central turbulent jet introducedintoa fluidizedbed equippedwith a V-grid was measured using ozone as a non-reactive tracer. The velocity of the jet at theapexof theV was kept constant at 93.5 m/s whereas the superficial velocity along theV-grid was varied from Umf to 3Umf.
Themass transfercoefficientfrom the jet to thedensebed was calculated from amodelwhich took intoaccountthecurvatureof the jet-densebed interfilce-
