The thermal diode allows the 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, whilst 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-demensional model. Distributions of temperature and mass flow rate are obtained for steady-state laminar flow. Numerical calculations are performed for the onset of motion of the fluid from rest. It is shown that the geometrical and thermal parameters have an influence on both the steady-state flow rate and the problem of global flow initiation from the rest.
