Abstract: Turbines are typical energy conversion devices used in the electricity, shipbuilding, and aviation industries. Based on research on traveling wave energy acquisition methods, a novel kind of built-in traveling wave turbine is created. The effects of traveling wave turbines on energy harvesting characteristics under varying wave numbers are investigated through numerical simulation, with equivalent wave amplitudes being dimensionless. By analyzing the structure of the convection field, the mechanism of energy conversion was elucidated. It is revealed that increasing the wave number can enhance the energy absorption efficiency of the traveling wave plate, with the maximum efficiency of the double wave numbers exceeding that of the single wave number by 3.01 %. With the rise in dimensionless amplitude while keeping the wave number constant, the energy absorption efficiency of the traveling wave plate follows a tendency of initially increasing and then decreasing. Incrementing the wave number and dimensionless amplitude can to some extent boost the power coefficient of lateral force. Through flow-field analysis, it is established that the best position for energy acquisition of the traveling wave plate predominantly lies in the plate's rear section, elevating the wave number of the traveling wave plate serves to thereby enhancing energy utilization efficiency.
