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 mcm 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.
