The heat transfer analysis presented in this study deals with the thermal performance of the helix slow-wave circuit for TWT. The current paper estimate the temperature of helix accurately through finite element software ANSYS. The expansion of rods makes the helix concave or convex at different position. Thermal strain made the radius of the tape increased overall, so the phase velocity decreases...
A simulated model has been established to calculate the temperature of helical slow-wave circuits accurately. The Finite Element Method software ANSYS was used to analyze the thermal distortion of the helical slow-wave circuit of TWT. The thermal analysis results show the thermal stress makes helical tape concave at the positions contacting with rods and convex at the part between the two rods, and...
