Abstract: Ratchet effect (net transport without any obvious bias) has been obtained in a periodic potential system. In the present work, in contrast, the net transport of particles is obtained numerically in a potential-free system with friction coefficient in the form of a traveling wave and driven by a zero-mean sinusoidal force. The nature of particle trajectories and hence the direction and magnitude of the particle current strongly depend on the ratio (r) of the frequencies of the friction coefficient and the periodic drive. The effect of the amplitude of the two periodic functions on the net current is also investigated.
