Stagnation point flow of viscoelastic nanomaterial over a stretched surface
Results in Physics, 2018 Present communication aims to discuss magnetohydrodynamic (MHD) stagnation point flow of Jeffrey nanofluid by a stretching cylinder. Modeling is based upon Brownian motion, thermophoresis, thermal radiation and heat generation.

Simulation of flight test conditions in the Langley pilot transonic cryogenic tunnel [PDF]
The theory and advantages of the cryogenic tunnel concept are briefly reviewed. The unique ability to vary temperature independently of pressure and Mach number allows, in addition to large reductions in model loads and tunnel power, the independent ...

The Bitter Taste of Brazil's Temporary Import Ban on Robusta Coffee
Agribusiness, EarlyView.ABSTRACT Brazil, a leading Robusta coffee producer and exporter, faced a significant drought in 2016–2017, which drastically reduced production and depleted stocks. Consequently, Brazil temporarily permitted the import of one million 60‐kg bags of Robusta coffee in the spring 2017. An import ban was imposed shortly afterward due to lobbying by domestic

Unsteady stagnation-point heat transfer during passage of a concentrated vortex [PDF]
The unsteady boundary layer due to a single rectilinear vortex filament approaching a 2-D stagnation point is investigated. Assuming the vortex remains far from the surface, incompressible potential flow theory is used to determine the time dependent ...

Regulating Airflow Using Hybrid LCN for Soft Pneumatic Circuits
Advanced Intelligent Systems, EarlyView.To address more autonomous soft robots with embodied control and regulation systems, herein, a liquid crystal network‐based fluid regulator that can be manipulated through multiphysical stimuli is proposed. Aided by finite element modeling for thermal actuation, regulators are designed and incorporated into fluidic circuits and demonstrate that they ...

Energy Procedia, 2012 AbstractHigh temperatures occurring during stagnation conditions can be very detrimental to the reliability, durability and safety of solar thermal systems. Various approaches to mitigate the effects to stagnation have been employed in the past, however as collector and system efficiencies improve, and larger solar systems are installed, the need for ...
