✦ Synopsis

Abstratz

-By applying the technique of one-shot thermal input, particle-to-gas heat transfer coefficients have been obtained for glass beads-air system in the range of Reynolds number from 5 to 229. The obtained heat transfer coefficients are well represented by a correlation, eqn (14), proposed by Wakao ef al. Sensitivity test on the experimental results shows that at low flow rates the particle-to-gas heat transfer cannot he a controlling step in the overall heat transfer process.
