This paper presents a review of the many problems associated with ship model testing, in particular in regard to the study of cavitation on marine propellers. After dealing with some basic considerations on the process of cavitation and its effects on ship propellers, the general problem of obtaining cavitation similarity in model testing is considered. An account is given of the present methods employed in propeller testing in cavitation tunnels. The difficult subject of scale effects and cavitation scaling is touched upon. It is shown that a vast improvement in ship model testing can be obtained when in a towing tank the air pressure can be reduced according to the predetermined similarity criteria. Such a facility is now nearing its completion at the Netherlands Ship Model Basin. Descriptions of this depressurized towing tank and of the tests to be performed and the test techniques applied are given.
