A Circular Towing Tank for Calibrating Plankton - net Flowmeters
نویسنده
چکیده
A specially designed circular towing tan~ was developed at the Northeast Fisheries Center (NEFC) for calibrating plankton-net flowmeters . ashore in order to provide more accurate volume estimates and to save valuable shipboard time. Results of a cross-calibration experiment with a flume in use at the Massachusetts Institute of Technology (MIT) demonstrated that calibration factors produced by the NEFC tank are more precise than those either from the MIT flume, from the flowmeter manufacturers, or from present methods used at sea.

During design spiral of a merchant ship or a naval vessel, it is important to perform towing tank tests in order to measure its performance either in calm water maneuvers or in waves for seakeeping performance. Also, to optimize a hydrodynamic design, towing tank tests are advantageous.This article presents the results of an applied research project. The objective of this project is to design a...

An inexpensive yet portable device for calibrating four different flow meters in the undergraduate fluid mechanics laboratory was designed and constructed. The apparatus contains a rotameter, a turbine-type meter, a venturi meter, and an orifice meter. All four meters are calibrated simultaneously using a volumetric measuring tank. Results obtained by undergraduate students are presented, and a...

A procedure is proposed to perform ship hydrodynamics computations for a wide range of velocities in a single run, herein called the computational towing tank. The method is based on solving the fluid flow equations using an inertial earth-fixed reference frame, and ramping up the ship speed slowly such that the time derivatives become negligible and the local solution corresponds to a quasi st...

Traditionally the resistance of ships has been determined using towing tank experiments. Over the past two decades increased computational power has allowed numerical approaches to replicate and potentially start to replace towing tank experiments. This work investigates the quality of results that can be achieved using a commercial Reynolds Averaged Navier Stokes (RANS) flow solver, ANSYS CFX ...
