Description 1049-1056
Towing tanks experiments were conducted to
study the behavior of flow on a model of underwater vehicle with tango shape of
nose. Length of model and prototype vehicle is 1 and 32
meters, respectively. First the method of underwater model test is evaluated by
unequal Reynolds number. An accurate method has been suggested for scaling of
results between model and main submarine in underwater testing. Suitable depth
for ignoring the free surface effects has been suggested. After underwater test
in towing tank and extracting the results, the CFD results have been compared.
At last, for more validation of results, four groups of experimental formula
for submarine bare hull resistance in deep water have been presented. Finally,
the comparison tables and diagrams show the accuracy of each of these six
methods in the calculation of submerged resistance of submarine and present an
optimum resistance coefficient for this submarine.
