| Abstract | ||
| The collapse of Nitrogen gas bubbles in the bio tissues of Divers who surface too quickly to the sea level is studied. In this paper, the effects of suction process on the collapsing of gas bubbles with constant ambient obtained. The mathematical model is formulated by Fick, and concentration equations and then solved by analytical method. The collapse of gas bubbles is affected by tissue concentration diffusivity and void fraction. Results showed that, the suction process activates the systemic blood circulation and accelerate the collapsing of gas bubbles in the bio tissues to avoid the incidence of decompression sickness (DCS) | ||
