“…To achieve a simulation of the chemical reaction, the properties of CO 2 and soda lime are analyzed. The chemical reaction between soda lime and CO 2 is an exothermic reaction and generates humidity (Nuckols et al 1985 ). A liquid and gas phase process occurring within the reaction is identified which must be taken into account when modeling the reaction (Olutoye & Eterigho 2005 ).…”

A mixture model simulation is presented by modeling the axial scrubber in a Closed Circuit Rebreather (CCR). The mixture model is a good substitute for the full Eulerian multiphase model because the interphase laws are unknown in this case. Analysis of mesh size, mesh type and inflation are made to independently characterize their accuracy by means of convergence before further comparisons with experimental data. The importance of mesh refinement is demonstrated near the wall with satisfactory results seen on the near grid wall of the boundary where a finer mesh is utilized. The contribution of inflation and grid independence to the accuracy of the model is presented in the results section.

“…The flow can be classified as laminar in CCR scrubbers (Nuckols et al 1985 ). Laminar flow is a type of gas or fluid flow in which the fluid travels smoothly or in regular paths, in contrast to turbulent flow in which the fluid undergoes irregular fluctuations and mixing.…”
