Startup Characteristics of Dredging Thermal Protection Structures

气体物理
Dredging thermal protection, as a semi-active thermal protection method, is characterized by its simple structure and the absence of the need to carry additional coolants, making it suitable for the leading edge thermal protection of hypersonic vehicles.

Coping with change: Interactive effects of anthropogenic change influence the breeding success and survival of a desert‐dwelling cooperative breeder

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Habitat modification and climate change are major threats to biodiversity. Using 38 years of data (1985–2023), we examined their combined influence on a desert‐dwelling cooperative breeder's reproductive success and projected the likely magnitude of future effects of ...

Evaluation of near-wall solution approaches for large-eddy simulations of flow in a centrifugal pump impeller

Engineering Applications of Computational Fluid Mechanics, 2016
The turbulent flow in a centrifugal pump impeller is bounded by complex surfaces, including blades, a hub and a shroud. The primary challenge of the flow simulation arises from the generation of a boundary layer between the surface of the impeller and ...

Optimization Design of a Winch Suction Underwater Dredging Robot Using Orthogonal Experimental Design

Journal of Marine Science and Engineering
In marine engineering and water conservancy projects, dredging often occurs due to silt accumulation, which can impede the long-term development of water ecosystems and water storage systems. To enhance dredging efficiency and the performance of dredging

Integrating experimental and observational approaches facilitates scaling species interactions to biodiversity patterns

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract To investigate how niche and fitness differences determine the outcome of species interactions and shape local biodiversity patterns, research has typically focused on either simplified experimental systems that test specific mechanisms or observational studies where ...

Sustainable sediment management in Jordanian dams: Feasibility, economic viability, and agricultural reuse potential [PDF]

Journal of Water and Land Development
Jordan has long faced severe water scarcity, which has significant implications for agriculture, industry, and domestic consumption. This crisis is further exacerbated by climate change, population growth, regional conflicts, and unsustainable water use.
