A mathematical model has been developed and numerical 
calculations of heat transfer have been performed for a horizontal 
heated cylindrical base with transverse sectional finning under the 
conditions of free-convective flow of an external heat-transfer agent. 
The effect of concurrent flows from lower fins on the heat transfer 
of upper fins has been studied. Local thermal characteristics of individual 
sectional fins on different portions of the cylindrical base and total 
heat fluxes removed by a finned surface have been determined. Results 
of the calculation have been compared to experimental data and satisfactory 
agreement of them has been obtained.
