eat transfer in multilayered direct-flow cooling systems with unilateral heating

Relations are obtained to calculate the temperature fields, heat fluxes, and corrected heat-transfer coefficients for multilayered direct-flow cooling systems under conditions of unilateral thermal loading. The solution is analyzed from the viewpoint of intensifying heat transfer and thermally insulating the structure. The solution is checked experimentally on a two-layer cooling system of the channel type $(\rm Re = 10^2$–$2\times 10^4,\rm Pr = 5$–$9)$.
