Abstract
This paper describes elucidation of propulsion mechanism of white blood cell with driving force by concentration gradient using computational model. In our previous experiments, it was found that the white blood cells move when the concentration gradient on the membrane is opposite to the concentration gradient of surrounding fluid. To investigate these phenomena by computational model, transport process of concentration near the cylinder with consideration of absorption factor and diffusion coefficient ratio. It is concluded that the opposite gradient can be generated when the proper diffusion coefficient ratio and absorption factor.
