Dynamics of Submerged Towed Cylinders 



The range of f , and £3 will be taken to be between zero and unity, 

 the latter limit representing well- streamlined, gradually tapering 

 nose or tail, eind no flow separation; it is obviously much more likely 

 for f , to approach unity than for fg. In the case of a blunt tail, on 

 the other hand, fg "*" 0, 



IV. EQUATION OF MOTION AND BOUNDARY CONDITIONS OF [ 26] 



The equation of nnotion given by Eq. (10) is not identical to 

 that previously derived by Paidoussis [ 26] . The difference is in the 

 frictional terms, because of the different manner in which frictioncil 

 forces were resolved in [ 26] . The boundary conditions are identical. 



As we shall make use of the results obtained in [ 26] , we give 

 the equation of motion below, for reference. 



The equation of motion and boundary conditions used in the 

 'new theory' presented in this paper are believed to be more self- 

 consistent than those of the 'old theory' of [ 26] .
