Numerical calculation of ship wave resistance based on linear theory

In order to predict the ship model wave resistance accurately and provide theoretical basis for a real ship optimization, a numerical calculation method base on C.C.Hsiung method (linear theory and using tent function to represent ship hull surface) and Noblesse new slender ship theory was developed for computing Wigley hull wave resistance. By comparing and analyzes the calculation results and model test results, the comparison results show that both methods can reflect the size of ship wave resistance, and the theoretically results and the test results of Noblesse´ new slender ship theory show better agreement.
