Simulation of Ship on Head Waves using CFD Analysis

For modelling and analysing fluid transport events, computational fluid dynamics (CFD) is one of the most crucial techniques. It is frequently applied to understand flow patterns and dynamic effects brought on by fluid motions in a variety of engineering fields. Over the past two decades, CFD has made considerable strides in the field of maritime technology, particularly in the area of ship hydrodynamics. For a Panamax bulk carrier measuring 217 metres in length, HSVA conducted model experiments in 2009 for a variety of Froude values and head waves with two distinct wave durations. Significantly less than the ship length were the two wavelengths that were tested. As a result, it is reasonable to assume that the ship motions are negligible. Accordingly, the majority of the additional wave resistance is brought on by wave reflections (diffraction) off the ship's bow. Two Froude numbers were simulated for both head waves and calm water. The calculated results for both simulated Froude numbers in calm water and in waves demonstrate a good agreement with the data. For the calm water condition at the lowest Froude Number, the maximum deviation from the measurement is less than 5%
