【Abstract】In order to develop the heating elements for electrically heated tobacco products (eHTPs) efficiently, an electro-thermal simulation model for heating blade was established by using simulation software. The temperature distribution in two kinds of heating blades under different voltages was taken as the objects to verify the consistency between the simulation values and the experimental values. The results are as follows. 1) The simulation values agreed with the experimental values generally, and the trends of their axial and radial temperature distribution showed good consistency. 2) Both the simulation result and the experimental result indicated that the temperatures differed significantly in the blades; the axial temperature difference reached 250 °C and the radial temperature difference was about 50 °C under normal working conditions. It suggests that the electro-thermal simulation is suitable for studying the temperature distribution in the heating elements for eHTPs, and the study results provide a reference for the design and development of the heating elements.
