The effectiveness of the heat transfer fluid pipe orientation angle inside a latent heat thermal energy storage system

open access: yesCase Studies in Thermal Engineering, 2022
Latent heat thermal energy storage systems exhibit a significant performance over other thermal energy storage systems. The performance of these particular systems during melting/solidification is influenced by their orientation.

Orientation angle and the adhesion of single gecko setae [PDF]

open access: yesJournal of The Royal Society Interface, 2011
Abstract We investigated the effects of orientation angle on the adhesion of single gecko setae using dual-axis microelectromechanical systems force sensors to simultaneously detect normal and shear force components. Adhesion was highly sensitive to the pitch angle between the substrate and the seta's stalk.

Orientation Angles of a Pulsar’s Polarization Vector [PDF]

open access: yesThe Astrophysical Journal, 2006
A statistical model of the polarization of pulsar radio emission is used to derive the general statistics of a polarization vector's orientation angles. The theoretical distributions are compared with orientation angle histograms computed from single-pulse, polarization observations of PSR B2020+28.

Damage behavior in quasi-isotropic CFRP laminates with small fiber orientation angle mismatch

open access: yesMechanical Engineering Journal, 2016
The use of carbon fiber reinforced plastic (CFRP) has contributed in producing light-weighted and strong aircraft structures. However, the low impact resistance of CFRP makes it easier for internal damages to occur.

A Modified Four-Component Decomposition Method With Refined Volume Scattering Models

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
In this article, a modified four-component decomposition method with refined volume scattering models is proposed for polarimetric synthetic aperture radar (SAR) image processing. In the new decomposition method, after the orientation angle compensation,

Flow-induced orientational change of aqueous solution of polymer after an abrupt expansion in planar channel flows

open access: yesNihon Kikai Gakkai ronbunshu, 2014
Flow-induced orientational changes of an aqueous polymer solution in planer channels have been studied utilizing optical rheometric technics. Two kinds of 1:4 abrupt expansion channels with the same width and different heights of 1 mm and 0.2 mm were ...

Investigation of steel fibre pullout and modeling of bridging behaviour in SFRC

open access: yesEngineering Structures and Technologies, 2012
By adding fibres to concrete mix the objective is to bridge discrete cracks providing for some control to the fracture process and increase the fracture energy. Fibres become active mainly when cracking starts and deformation of the fibre occurs. Pullout

Receiver orientation and event back-azimuth estimation for downhole microseismic monitoring using a probabilistic method based on P-wave polarization

open access: yesFrontiers in Earth Science, 2023
Microseismic event back-azimuth is an indispensable parameter for source localization in downhole microseismic monitoring, and the accurate orientation of horizontal components of downhole seismic receivers is vital for reliably determining the event ...
