Bubble blood oxygenator - A a design analysis

The behavior of a bubble blood oxygenator is simulated by a dispersion model. The model equations are solved by both a variable step size-finite difference algorithm and a backward marching technique. The computed results indicate that blood oxygen saturation increases with increases in column diameter and glas flow rate. The bubble column is found to behave like a continuously stirred tank reactor at large values of either the column diameter or the gas flow rate. The performance of Shiley and Harvey H-200 bubble oxygenators was compared with the dispersion model. The results were found to be in good agreement. © 1981 Pergamon Press Ltd.
