In this paper, a new channel model is presented for molecular communications (MC), where a point source emitted by the transmitter undergoes three phases, with effect of convection dominating in the first two phases, whereas diffusion prevailing in the final phase. The point source obtains its initial velocity and passes through the nozzle of the nanomachine transmitter in the first phase, followed by a deceleration process in the second phase. The free diffusion model is considered in the third phase. Based on this channel model, the energy transfer issue for two-way MC system is also taken into account, in which one of the transceivers is assumed to have abundant information molecules from its ambient environment, whereas the other one obtains the information molecules by implementing the simultaneous molecular information and energy transfer (SMIET). Finally, analytical bit error rate (BER) expressions are validated by computer simulations. Our results suggest that the symbol duration and the SMIET order significantly influence the BER performance in our two-way MC system.
