The wall-to-suspension heat transfer coefficient increases with increasing solids flux from ∼430 to 1120 W/m2 K.

Empirical and modeling approaches were applied to compare experimental and predicted values.

The high temperature of the circulating powder leads to significant savings in investment and operating costs.
