The thermal diode allows heat to be transferred in one direction, preventing the transfer of heat in the opposite direction. Two new models of the thermal diode are presented in this paper. The first model describes the thermal diode heated simultaneously from below and symmetrically from the sides, while the second model demonstrates the thermal diode heated from a lower part of one side and cooled from the upper part of the opposite side. The analysis of fluid flow and heat transfer is based on a one-dimensional model. Distributions of temperature and mass flow rate are obtained for the steady-state turbulent flow. It is shown that the geometrical and thermal parameters have an influence on the steady-state flow rate.
