Abstract
In this paper, the effective diffusion coefficient of the coupled Brownian ratchet is studied. Langevin equation is used to describe the coupled Brownian ratchet model, and the Runge-Kutta algorithm is used to solve the equation. The average velocity of the coupled Brownian particle is obtained, and the effective diffusion coefficient of the coupled ratchet is further calculated. The numerical calculation method of the effective diffusion coefficient of coupled Brownian particles has been widely used in many research fields. By using this numerical strategy, researchers can deeply understand the dynamic behavior of complex systems and provide theoretical support for the research and application in related fields.
