The main current communication method is electromagnetic (EM) wave communication. Then, it is necessary technology for human life. EM wave system has conveniences that high-speed and large capacity communication. On the other hand, it also has disadvantages that it requires much energy and the facilities. In contrast, molecular communication (MC) that uses biological molecules as an information carrier is noticed as a new communication method, because it requires little energy and is expected application for micro-scale. However, in general MC is difficult to communicate at high-speed and to control communication itself comparison with EM wave communication. Because most of MC is diffusion-based. In this study, numerical simulation for the promoting effect of concentration diffusion by flow caused by the movement of a circular object is performed to solve the problem of communication speed. As a result, diffusion phenomenon was promoted in responde to the object condition.
