In eacn case, t e use of flow visualization, velocity mapping, and gas mixing can be used as a valuable design tool for system development or modff1cat10n- prov1ding the isothermal scale model is based on the use of appropriate model sizing techniques. We expect that such mode 11ng techmques will be useful for future unique furnace design. Furthermore, In addition to improvements in data acquisition and accuracy for flow and mixing measurements, we expect to advance the use of this general type of modeling to gas/sol1d systems.
