Abstract
In a previous study (Chen and Weinstein, 1993) in which the literature was reviewed, the authors determined the shape and extend of the void formed by a horizontal jet using X-ray imaging. The void fraction distribution around the jet and the tracks of the bubbles formed by the jet gas leaving the void were described. In the present study using the same experimental facility, the horizontal jet was heated and temperature surveys were obtained in the bed. These data provide a comparison of the picture of the jet structure obtained from the spread of the heated gas with that previously obtained from the spread of the jet mometum. In addition, in the present study the superficial velocity of fluidizing gas (through the grid) was varied to determine its effect on the jet penetration and dispersion.
