Abstract:
This research addresses the difficulties in determining the manoeuvring characteristics of a slender body through a fluid. This work has direct applicability in many areas of hydrodynamics and aerodynamics. For example the manoeuvring of ships and submarines through water or the manoeuvring of missiles or aircraft through the atmosphere for cases where the compressibility of the air is not a significant factor. The research is approached by looking at both a slender body theory in potential flow (inviscid) and a slender body theory in Oseen flow (viscous). The differences between these two approaches are considered and the force expressions are found for both cases. This work gives rise to a discrepancy between the lift force expressions (sometimes referred to as the normal or side force) for the two approaches which leads to some interesting comparisons and conclusions. This discrepancy in the lift force calculation has in fact been noticed separately by both aerodynamicists, Alien [3], and hydrodynamicists, Clarke [12] and Newman [27]. The work presented here looks at the reasons for this force discrepancy and links slender wing theory and slender body theory together.
