Example optimisation plots indicating the length of device and flow speed for which 90% saturation is achieved: (a) The oxygenation levels at \(x=1\) as a function of distance through the device z as the transverse flow speed ratio, ν, is varied (b) The critical length of the device to ensure the blood has reached 90% saturation at \(x=1\), as a function of transverse flow speed ratio, ν.
