Enhancement in Rejected Heat from Heat Sinks Using High Flexible Winglets with Large Deformation and Low Blockage Effect [PDF]
Iranica Journal of Energy and Environment, 2022 This paper presents an original concept of using high flexible flapping vortex generator in a heat sink for airside heat transfer augmentation. The proposed thin winglet, made with an elastic sheet, is responsible for increasing the cooling rate and ...

Liquid Transport Due to Light Scattering [PDF]
, 2006 Using experiments and theory, we show that light scattering by inhomogeneities in the index of refraction of a fluid can drive a large-scale flow. The experiment uses a near-critical, phase-separated liquid, which experiences large fluctuations in its ...

Large deformation and plates [PDF]
PAMM, 2012 AbstractIn the simulation of deformations of plates it is well known that we have to use a special treatment of the thickness dependence. Therewith we achieve a reduction of dimension from 3D to 2D. For linear elasticity and small deformations several techniques are well established to handle the reduction of dimension and achieve acceptable numerical ...

Finite strain elastoplastic constitutive model of saturated soil
Shuiwen dizhi gongcheng dizhiDuring the construction of urban underground engineering projects, soils are typically in a saturated state, and many underground engineering accidents are closely related to the large deformation behavior of saturated soils.

An approach to elastoplasticity at large deformations [PDF]
European Journal of Mechanics - A/Solids, 2013 Finite plasticity theories are still a subject of controversy and lively discussions. Among the approaches to finite elastoplasticity two became especially popular. The first, implemented in the commercial finite element codes, is based on the introduction of a hypoelastic constitutive law and the additive elastic-plastic decomposition of the ...
