Experimental investigation of the boiling heat transfer 
of refrigerants R12 and R227 on inclined tubes placed in granular 
beds has been carried out. The plots show the reduced coefficient 
of heat transfer as a function of the reduced specific heat flux for 
various positions of a tube placed in different granular beds.
