Description 1013-1022
Present study
consists the effect of variation of the vehicle length on the hydrodynamic
forces and moments of axisymmetric underwater vehicles due to angle of attack.
Five different vehicle lengths are used for this study (L/D varying between 10
and 15) by experimental, numerical and empirical methods. Experimental
investigation is done in a tow tank using a VPMM. Numerical analysis is carried
out using commercial CFD code Fluent 6.2. The empirical estimation is based on
method suggested by Allen & Perkins. Results show that the linear
coefficients vary linearly with L/D, while the nonlinear coefficients vary
nonlinearly with L/D for the range tested.
