Three blades or four, how propeller design balances speed, power, and cavitation
Ship propellers are a constant compromise between efficiency, vibration, cavitation, and power delivery. This video explains why adding blades can solve serious mechanical problems, and why engineers ...
MAN Diesel & Turbo optimizes the efficiency of ship propellers using cutting-edge CFD simulation methods The layout of ship propellers is a balancing act between optimal power conversion and the ...
MORE THAN 1,000 metres below the surface of the oceans, darkness reigns. For animals living in this perpetual twilight, vision is irrelevant; acoustic signals, instead, are how they navigate, ...
Combination of carbon, glass and epoxy resin produces a strong replacement for nickel/aluminum/bronze metal, the current propeller standard. Damage-tolerant reinforcing fabric strengthens highly ...
LOGAN, UTAH - A popular backyard science experiment led a team of fluid dynamics experts to a new math formula that more accurately predicts cavitation and its damaging effects. A common culprit in ...
