Definition and Meaning of Wigley Hull Forms
A Wigley hull is a specific type of ship hull form characterized by its smooth, continuous lines and symmetrical shape. It is often used in hydrodynamic studies due to its simplicity and effectiveness in modeling various hydrodynamic behaviors. The hull form is typically represented in a mathematical model that allows for the analysis of its performance in water. Understanding the definition of Wigley hull forms is essential for evaluating their effects on hydrodynamic performance, particularly in terms of resistance and stability.
How to Use the Experiments and Calculations on Four Wigley Hull Forms
Utilizing the data from experiments and calculations on four Wigley hull forms involves several steps.
