Hypobaric Decompression Sickness Model Development. Part 1. Diffusion of Inert Gas From A Viscoelastic Fluid (Blood) Into an Expanding Gas Phase

Abstract

Bubble growth within a volume of isothermal viscoelastic liquid containing uniformly distributed dissolved gas is considered. A nonlinear viscoelastic constitutive equation is used as a blood model. The problem of characterizing this growth-by-mass-transfer is being treated extensively, in order to better understand both the behavior of bubble growth due to supersaturation and its effects on altitude decompression sickness.
