We present the analytical solution and a physical analysis of the thermal constriction resistance for a configuration in which the heat flux lines undergo a π reversal. The configuration considered is an adiabatic cylinder except one of its bases, where three boundary conditions are imposed: a circular heat source, three annular surfaces which correspond to two adiabatic surfaces and one isothermal surface (heat sink). We study the size influence of the source, of the heat sink, and of the cylinder thickness on the thermal constriction resistance. To cite this article: V. Gatto et al., C. R.
