Abstract

An analytical investigation was carried out to determine the design conditions, for a ducted propeller unit operating in water, providing optimum suppression of cavitation when the forward speed, depth and body drag are given. The selection charts were constructed in detail for propellers using the NACA 65 series blades. The results indicate the pumps of generally higher flow rates are more desirable than those that have been employed in the few units actually constructed.
