Numerical Simulation and Uncertainty Analysis of Wave-Co-Current Interaction with Irregular Waves

Uniform current effects on the characteristic of irregular waves along with its uncertainty are presented considering wave-current interaction in the actual ocean environment. First, relative tests of interaction of irregular wave and uniform current are conducted in the circulating water channel at...
