Heat exchange of dynamic powder beds with a heat-transfer surface. II. A dust-laden gas flow

Heat exchange of a dust-laden gas flow with the wall of a cylindrical channel in laminar and laminar-to-turbulent transitional regimes of gaseous-phase motion is studied experimentally. Corundum with a particle size of 40 µm was used as the solid phase while air was used as the carrier gas. Experime...

Zusammenfassung:Heat exchange of a dust-laden gas flow with the wall of a cylindrical channel in laminar and laminar-to-turbulent transitional regimes of gaseous-phase motion is studied experimentally. Corundum with a particle size of 40 µm was used as the solid phase while air was used as the carrier gas. Experimental values of the heat-transfer coefficient are obtained and approximate dependences for the Nu number are proposed.[PUBLICATION ABSTRACT]
