A review of modelling techniques for floating offshore wind turbines

Wind Energy, Volume 25, Issue 5, Page 831-857, May 2022., 2022
Abstract Modelling floating offshore wind turbines (FOWTs) is challenging due to the strong coupling between the aerodynamics of the turbine and the hydrodynamics of the floating platform. Physical testing at scale is faced with the additional challenge of the scaling mismatch between Froude number and Reynolds number due to working in the two fluid ...

Does Entrepreneurship Work? Understanding What Policy Entrepreneurs Do and Whether It Matters

Policy Studies Journal, Volume 49, Issue 4, Page 968-991, November 2021., 2021
When a major policy change occurs, policy entrepreneurs—advocates who devote substantial time, energy, and resources to campaigning for a specific policy outcome—are often credited as critical influences. However, there has been a little quantitative, large‐n cross‐sectional study of whether policy entrepreneurship effectuates policy change, how policy

Annual Optical Performance of a Solar CPC Photoreactor with Multiple Catalyst Support Configurations by a Multiscale Model

International Journal of Photoenergy, Volume 2018, Issue 1, 2018., 2018
In this work, the seasonal and yearly optical performance of supported catalyst CPC solar photocatalytic reactors has been theoretically analyzed. A detailed model for the optical response of the anatase catalyst films is utilized, based on the characteristic matrix method, together with Monte Carlo ray tracing simulations.
