GENERALIZATION OF EXPERIMENTAL DATA ON HEAT TRANSFER AND HYDRAULIC RESISTANCE OF CHANNELS WITH SPHERICAL PROTRUSIONS

Experimental investigations of hydraulic resistance and heat transfer in channels with intensifi ers in the form of systems of spherical protrusions have been generalized in a wide range of working and design parameters. A unifi ed approach to the correlation of experimental data of various investigators with account for the differences in the geometry of heat transfer surfaces has been worked out. Unifi ed universal dependences for the coeffi cients of hydraulic resistance and heat transfer in channels with spherical protrusions are obtained.
