Study on turbulence field by means of DISA hot wire anemometry is described for: 1. Nozzle: time-averaged velocity

turbulent fluctuation velocity and turbulence intensity are shown to possess similarity when represented on dimen-sionless coordinates

and linear correlations were obtained for maximum turbulent fluctuation velocity and maximum turbulence intensity. 2. Fluidized Bed: time-averaged velocity

turbulent fluctuation velocity and turbulence intensity vary dramatically in distributor plate zone

which therefore defines a region of high mass and heat transfer. 3. Top-Fired Hot Stove: velocity and turbulence fields for a proposed design show a high degree of uniformity

which could be relied upon for prolonged stove life

high thermal efficiency

and energy saving.
