Lacustrine and fan‐delta sediments in syn‐rift lake basins

The Depositional Record, Volume 11, Issue 3, Page 857-892, June 2025.
A consistent model for the sequence framework and depositional pattern of asymmetric half‐grabens in syn‐rift lake basins bounded by active faults has been established, complementing existing models for marine rift successions. Syn‐rift lake basins are characterised by relatively small dimensions, steep slopes, poorly developed shoreline strata ...

Discontinuity of lift on a hydrofoil in reversed flow for tidal turbine Application [PDF]

, 2017
This work presents an experimental investigation of a hydrofoil in reversed flow configuration in the context of marine current turbine development. Experiments consist in hydrodynamic force measurements and PIV flow observations on a NACA 0015 hydrofoil,

Hydrodynamic Study of Flow-Channel and Wall-Effect Characteristics in an Oscillating Hydrofoil Biomimetic Pumping Device

Biomimetics
To clarify how flow-channel configuration and wall spacing govern the hydrodynamic performance of an oscillating-hydrofoil biomimetic pumping device, this study conducted a systematic numerical investigation under confined-flow conditions. Using a finite-

Multi‐Year Nutrient and Organic Carbon Mass Balance of a Young Boreal Hydroelectric Reservoir Complex

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 5, May 2025.
Abstract Reservoir construction can alter the transport and export of nutrients and organic matter by rivers to coastal areas. However, influences from construction within the first years after flooding are not well understood. Here we present a 9‐year study of La Romaine Hydroelectric Complex, composed of four cascading boreal reservoirs sequentially ...

A Tale of Evolution of the Central Indian Tectonic Zone (CITZ) With Glimpses on Pre‐Suture Plate Margin Depositional History

Geological Journal, Volume 60, Issue 2, Page 404-430, February 2025.
Present study explains the current understanding about the complex evolution of the CITZ. New zircon geochronological data from Mahakoshal Basin is used to document the pre‐suture history of the southern margin of Bundelkhand Craton where Mahakoshal Basin developed as a back‐arc basin and remained open even after 1700 Ma.

Pore Water Pressure in Sand Bed under Oscillating Water Pressure [PDF]

, 1984
In this paper the theoretical method to analyse the pore water pressures in the sand bed under the oscillating water pressure is developed. In the former researchs the validity of the theoretical treatment for the one-dimensional problem has been ...

Wind Turbine Optimization by Blade Element Momentum Method and Particle Swarm Optimization Technique

Journal of Engineering, Volume 2025, Issue 1, 2025.
The aerodynamic efficiency of wind turbines is greatly influenced by the shape of their airfoils. In this study, four airfoils were optimized to enhance the performance of a small horizontal axis wind turbine. The optimization process involved adjusting the thickness and camber of the airfoils using the blade element momentum method and particle swarm ...

Identification of the vortex in the main flow passage of a multiphase pump and the relationship with pressure fluctuation

Energy Science &Engineering, Volume 12, Issue 10, Page 4394-4413, October 2024.
This study develops a method of identifying vortices in the impeller channel of the multiphase pump, and reveals the intrinsic connection between the vortices and pressure fluctuations in the main flow passage. These findings offer some suggestions for eliminating the influence of vortices and enhancing the pressurizing capabilities of multiphase pumps.

Dynamic Behavior of Sand Bed under Oscillating Water Pressure [PDF]

, 1986
Under the attack of storm waves, there are many destructions of coastal structures in the forms of sinking and sliding. These types of destructions will be in close relation to the dynamic behavior of sand bed around the structures.

A Soft Robotic Morphing Wing for Unmanned Underwater Vehicles

Advanced Intelligent Systems, Volume 6, Issue 6, June 2024.
This study presents the design and hydrodynamic characterization of a soft wing for implementation on underwater gliders. Through hydraulic actuation, the soft wing deforms and adjusts its lift‐to‐drag ratio, which ranges from −70% to +10% with respect to a rigid wing.
