Large-scale instabilities in a STOVL upwash fountain [PDF]
, 2005 The fountain flow created by two underexpanded axisymmetric, turbulent jets impinging on a ground plane was studied through the use of laser-based experimental techniques. Velocity and turbulence data were acquired in the jet and fountain flow regions

Exergy based modeling and optimization of solar thermal collector provided with impinging air jets
Journal of King Saud University: Engineering Sciences, 2018 The irreversible absorption of solar energy accompanied by emission for conversion into thermal energy takes place at the cost of exergy losses from the collector and the effectiveness of this conversion is evaluated in terms of exergy efficiency based ...

Advanced Materials, EarlyView.Elephant‐skin‐inspired crack networks are programmed in porous diatomaceous earth (DE)‐cement composites using substrate‐guided, stress‐concentration induced fracture. The resulting crack lattices act as capillary conduits that redistribute water, while the porous matrix stores moisture.

Rarefied planar jet and jet impingement flows [PDF]
AIP Conference Proceedings, 2012 This paper presents three sets of analytical exact solutions to collisionless gas flows from a two-dimensional exit. The first set is free plume expanding into a vacuum, and the other two sets are collisionless plume impingement at a vertically set plate.

Topological Point Defects in SmC* Liquid Crystals Under Mechanical Disturbance
Advanced Materials Interfaces, EarlyView.Tangetial air jet shear inducess island formation and nucleates topological point defects in uniform SmC films. Island bounded by edge dislocation loops shrink and transform into isolated point defects under continued shear. Mechanical perturbatio provides a controllable route for defect engineering in smectric liquid crystal thin films.
