Abstract Background This study introduces a numerical model designed to simulate interactions occurring between a wind turbine's tower and the surrounding soil, as well as between the nacelle, blades, and the surrounding environment. This simulation

A new semi analytical formulation is developed which models the dynamic behavior of offshore wind turbine with variable cross section and flexible foundation. The wind turbine tower is modeled using Euler-Bernoulli beam model while the soil-tower int

A flow model is developed to predict the fluid velocity in the nearshore zone. The model is a combination of 1-D horizontal wave model with 1-D vertical model. A new combination is suggested at the trough level. A comparison with the experimental dat
