Abstract |
|
|
| The concentration distribution around growing gas bubble in the blood and bio tissues of divers who ascend to surface too
quickly is obtained by Mohammadein and Mohamed model [12] for variant and constant ambient pressure through the decompression
process. The mathematical model describing this problem consists of four main equations: mass, convective diffusion, Fick’s and
Laplaces equations. The mathematical model is solved analytically to obtain the concentration distribution around a growing gas
bubble in biotissues. The growth of gas bubble is affected by initial concentration difference DC0, diffusivity of gas in tissue DT , the
constant Kd at decompression, surface tension s , initial void fraction f0. The relation between the growth of gas bubbleR(t) and time
t is obtained from the definition of the concentration distribution around a growing gas bubble in biotissues. The relation between the
growth of gas bubble and time is studied under the effect of two different values of initial void fractionf0,critical bubble radius Rc. The
present model is compared with Mohammadein and Mohammed model [12] |
