Controlling the Negative Pressure Caused by Water Hammer in Water Conveyance Pipe Lines Using Hydropneumatics Tank and Air Valves (A Case Study of Mehran City, Ilam Province) [PDF]

علوم و مهندسی آب و فاضلاب, 2017
Whenever and for any reason the velocity of the fluid ceases in the transfer line or water distribution networks, pressure waves will form in the pipe lines, which can produce a pressure several times more than a pressure pump’s output and lead to a ...

Cicada Wing‐Inspired Skeleton‐GO Networks in Melamine Foams for Multifunctional High‐Performance Composites

Advanced Science, EarlyView.
Inspired by the intricate microstructure of cicada wings, researchers developed a novel in situ skeleton‐graphene membrane architecture within lightweight foams. This bioinspired design dramatically enhances multifunctional performance: vibration attenuation time decreases by ∼83.3%, damping capacity increases by ∼179.3%, and compressive modulus rises ...

Relationship between the Basic Geometric Form and Hydrodynamic Characteristics of Water Hammer Pump

Journal of Fluid Science and Technology, 2010
This study focuses on water hammer pumps that can effectively use the water hammer phenomenon and allow fluid transport without drive sources, such as electric motors. An understanding of water hammer pumps' operating conditions and an evaluation of

Stochastic Entanglement of Deterministic Origami Tentacles For Robust Robotic Grasping

Advanced Science, EarlyView.
This study introduces an origami tentacle gripper to robustly grasp objects‐in air, underwater, and even in orbital space‐by exploiting a synergy between local, deterministic deformation programming and global, stochastic entanglements. A single origami tentacle can be designed to coil with a simple tendon pull.

Research on water hammer model and pressure pulsation of digital hydraulic valve control system

Advances in Mechanical Engineering
It is found through experiments that the amplitude, waveform and periodicity of the water hammer pressure pulsation under the continuous on/off of the valve in the digital hydraulic system are affected by the frequency of the valve switching valve, which

Gestational Hypoxia Disrupts Medial Ganglionic Eminence Progenitor Dynamics and Interneuron Development in Schizophrenia

Advanced Science, EarlyView.
FES‐derived MGE spheroids exhibit progenitor‐stage alterations in developmental trajectory and hypoxia‐responsive transcriptional programs, followed by functional disruption. Gestational hypoxia recapitulates impaired progenitor proliferation, shortened cell‐cycle progression, interneuron developmental abnormalities, and schizophrenia‐like behaviors in

Bio‐Inspired Gradient Coatings Enhance the Leading Edge Erosion Resistance of Wind Blades

Advanced Science, EarlyView.
Rain‐induced erosion of the wind turbine blade leading edge poses a critical challenge to maintenance and operation. Here, we propose a bio‐inspired approach for erosion protection utilising a platelet‐reinforced polyurethane coating with a graded through‐thickness architecture.
