Basic instrumentation techniques, measurement using strain gauges, equipment and methods for data acquisition. Introduction to advanced measurement techniques, such as Particle Image Velocimetry. Calibration of measurement equipment. Techniques for model construction. CFD programs, grid generation and visualisation.
How to carry out typical model tests, such as: resistance, propulsion, propeller open water, cavitation tests, seakeeping tests, tests with slender structures. In some cases, numerical simulations comparable to the model tests will be carried out. Uncertainty Analysis. Error sources in experiments and numerical calculations. Special considerations for full scale measurements.
