    Abstract: High pressure drop generated by a restriction orifice may result in a very low temperature, which can affect the piping material and may cause catastrophic piping failure if the operating temperature becomes lower than the minimum design temperature. This minimum design temperature is stated by piping ASME B31.3 code as -48°C. In such piping resear... Show More

    Abstract: Resistance forces of water affecting to the ship hull at every single time during ship motions change very complexly. For simulating the ship motion in 6 degrees of freedom on a bridge simulator, these forces need to be calculated. Previous studies showed that resistance forces were estimated by empirical or semi-empirical methods, basic hydrodynam... Show More
