| 内容記述 | In the ordinary model exlperiments, especially in the case performed in the Towing Tank, the frictional resistance,－which owing to the existence of laminar flow, expresses smaller count than the actual one,－enforces the experimenters to fit a trip wire at the model vessel for the purpose of inducing a turbulent flow along the model in the boundary-layer. With the intention of improving these clumsy procedure we, forseeing the working effects of the Circulating Tank in connection with the character of the resistance in the turbulent flow, performed a comparative research on the experiment tests in the 2 different types of Tank under the use of the identical fishing vessel model, with the following results obtained. 1) When, as in case of the fishing vessel, the ship-speed is fixed within 10 knots, or within the slow speed at which the vessel resistance is frictional, both E.H.P. and D.H.P. got at the Circulating-experiment Tank showed more approximate value inherent in the actual ship than in case of the towing-experiment Tank ; enabling the author to confirm the effect of the turbulent flow of the Circulating Tank. 2) In case of the ship-speed being over 10 knots, when most of the model resistance is wavemaking, no discrepancies were to be found in the two kinds of Tank ; either case showed an approximate value inherent in the actual ship. 3) In the experiments done at the Circulating Tank (14m.×2m.×1m.), no difrerence in the effects of scale ratio of the two similar model Lpp. 1.50m., 1.00m. was to be confirmed. | |||||
