Figure 2.
The image depicts a fluid flow diagram featuring a sinusoidal path between an inner diameter, labeled as "D sub i," and an outer diameter, labeled as "D sub o." The length of the flow path is denoted by "l," indicated by horizontal arrows at both ends. The flow path twists in a wave-like manner, creating two distinct flow channels. The annotations are clear and legible, highlighting how the dimensions relate to the fluid's movement.Finned module in the internal annulus of the sterilizer
