Seismic response of floating wind turbines due to seaquakes
Wind Energy, Volume 26, Issue 2, Page 145-162, February 2023., 2023 Abstract Vertical seismic waves, which are primarily due to pressure waves in the ground, can propagate with the same intensity in the seawater and impact floating bodies such as floating wind turbines (FWTs). Part of this wave can further propagate in the tower and generate large vertical accelerations in the nacelle. This paper presents a methodology

Wind Energy, Volume 24, Issue 9, Page 1045-1065, September 2021., 2021 Abstract Individual pitch control (IPC) is an effective and widely used strategy to mitigate blade loads in wind turbines. However, conventional IPC fails to cope with blade and actuator faults, and this situation may lead to an emergency shutdown and increased maintenance costs.

The collapse of a spherical cavity in a compressible liquid [PDF]
, 1963 This paper presents numerical solutions for the flow in the vicinity of a collapsing spherical bubble in water. The bubble is assumed to contain a small amount of gas and the solutions are taken beyond the point where the bubble reaches its minimum ...

Shape Morphing Programmable Systems for Enhanced Control in Low‐Velocity Flow Applications
Advanced Intelligent Systems, Volume 7, Issue 11, November 2025.A soft, Lorentz‐force‐driven programmable surface enables rapid, reversible shape morphing for active flow control. Integrating experimental, numerical, and modeling approaches, the system demonstrates effective modulation of near‐wall flow and momentum at low velocities, offering pathways for bio‐inspired aerodynamics and natural locomotion emulation.

Engineering Reports, Volume 6, Issue 4, April 2024.The novelty of this study is due to the analysis of Prandtl nanofluid model with Soret mechanism and chemically responding fluids. This suggested model is beneficial since it can significantly advance the domains of thermal and industrial engineering and this model is solved by EFDM. An important findings of the current investigations can be treated as,

A Note on the Linear and Nonlinear Theories for Fully Cavitated Hydrofoils [PDF]
, 1956 The lifting problem of fully cavitated hydrofoils has recently received some attention. The nonlinear problem of two-dimensional fully cavitated hydrofoils has been treated by the author, using a generalized free streamline theory.
