Parallel Plate Viscous Dampers [PDF]

, 1986
The subject of this investigation is to analyze the oscillation of multi-plates immersed in a viscous fluid and the damping forces. The concept of multi-plates oscillating in a viscous fluid with the view of using the plates as a damper is believed to ...

Study on the Development of Passive MR Damper with Displacement-Dependent Damping Characteristics

Journal of Fluid Science and Technology, 2010
In this paper, we propose a new concept of a magneto-rheological (MR) fluid damper, which is a passive MR fluid damper. The passive MR damper has no electrical devices, such as a sensor, power supply and controller, and hence, it has an advantage in ...

A Basic Study on Oscillatory Characteristics of Magnetic Fluid Viscous Damper.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1991
Basic studies of a magnetic fluid viscous damper are carried out theoretically and experimentally to clarify the effect of an applied magnetic field on the characteristics of a vibrating spring-mass system in the magnetic fluid. Experimental study shows that the application of magnetic field is effective reducing the resonance characteristics of the ...

Regulating Droplet Dynamics via Wormlike Micelle Networks: From Splash Suppression to Precise Confined Spreading

Advanced Science, EarlyView.
As displayed in Graphical Abstract image.tif, a molecular‐design strategy precisely tailors high‐speed droplet dynamics through programmed surfactant co‐assembly. The structural transition into an entangled wormlike micelle network completely suppresses stochastic splashing on fibrous substrates.

A Multidimensional Engineering Strategy Reprograms Microglia via Targeted and Sustained‐Release Extracellular Vesicles for Spinal Cord Injury Repair

Advanced Science, EarlyView.
A multifunctional EV‐based nanoplatform (Ang‐TEVs@Gel) was engineered via preconditioning, surface targeting, and ROS‐responsive hydrogel encapsulation to reprogram microglia. This system restored autophagy via miR‐664a‐3p/PIK3CA axis, cleared myelin debris, resolved neuroinflammation, and promoted axon remyelination, ultimately achieving robust motor ...

High‐Power Hybrid Nanogenerator With Multi‐Degree‐of‐Freedom Mechanical Coupling for Harvesting Water Wave Energy

Advanced Science, EarlyView.
A high‐power hybrid nanogenerator (HP‐HNG) with multi‐degree‐of‐freedom mechanical coupling is reported, integrating multi‐directional wave energy for output to achieve 1 + 1 > 2 energy harvesting. The HP‐HNG achieves a peak output power of 0.764 W, corresponding to a peak power density of 127.303 W m−3. At a wave frequency of 1 Hz, the HP‐HNG delivers

A numerical investigation of horizontal viscous gravity currents [PDF]

, 2009
We study numerically the viscous phase of horizontal gravity currents of immiscible fluids in the lock-exchange configuration. A numerical technique capable of dealing with stiff density gradients is used, allowing us to mimic high-Schmidt-number ...

Iron‐Tannic Acid Hydrogel Mediated Mild Photothermal Therapy Combined With Ferroptosis Enhances Anti‐Tumor Immunity in Colorectal Cancer

Advanced Science, EarlyView.
An injectable gelatin‐based tannic acid–iron hydrogel with mild photothermal therapy could not only induce immunogenic cell death, but also elicit ferroptosis of both tumor cells and tumor‐associated macrophages, resulting in DC maturation, T‐cell infiltration and down‐regulation of ferroptosis‐sensitive M2‐type TAMs levels.

Seismic Analysis Of Buildings Using Fluid Viscous Damper

, 2017
Now a day’s Earthquakes are happening in various parts of the earth. So buildings should be designed and constructed in such a manner that they will withstand the earthquakes. Non linear seismic assessment is a good tool in helping us to predict the seismic capacity. Many devices are used to improve the seismic capacity of the buildings.
