Experimentally studied the influence of operational and geometrical parameters on flow resistance and heat transfer in honeycomb seals. The relationship between the nature of changes in the degree of intensification of hydraulic resistance, heat and vortex structure in the space of the cell. The effect of blowing cooling air through the surface of the honeycomb structure on the thermal hydraulic characteristics of the seal.
honeycomb seal, hydraulic resistance, heat transfer, cooling air, cooling efficiency, operating reliability, service life, safe operation.
