11. The HeartAssist5 is an axial flow pump and the smallest of the full-flow LVADs. 12. Although multiple compression stages are needed, axial flow pumps work well with low-density fluids. 13. To illustrate the dependence, an expression for axial flow pump and fan is shown 14. Axial flow is theoretically more efficient and physically slimmer but requires higher technology to achieve.15. In 1903 Zoelly developed a multi-stage axial flow impulse turbine in collaboration with Professor Stodola. 16. SeaGen is made up of two axial flow rotors, each of which drive a generator. 17. Thrust was provided by a pair of 30 kN axial flow Rolls-Royce Avon turbojet engines. 18. High-head systems use high-pressure centrifugal pumps, and low-head systems use low-pressure axial flow propeller pumps. 19. Like the Jarvik 2000, DeBakey's device is a miniature axial flow pump, but it is inserted into the aorta. 20. The "'ASX "'was an early axial flow jet engine built by Armstrong Siddeley that first ran in April 1943.
