DOI: 10.1016/j.combustflame.2020.06.038
Abstract: Abstract In the present study, flame dynamics of free-falling contactless burning fuel droplets (pure and nanofuel) is investigated. A droplet under free fall undergoes acceleration resulting in progressive increase of its velocity (increase in Reynolds… read more here.

DOI: 10.1016/j.ijheatmasstransfer.2019.118821
Abstract: Abstract A novel multi-stage free-falling particle receiver design is proposed to improve the simple free-falling concept by enhancing the hydrodynamic stability and improving the radiation absorption of the particle curtain. The multi-stage design arising from… read more here.

DOI: 10.1088/1361-6382/abd142
Abstract: Galactic cosmic rays and solar energetic particles charge gold-platinum, free-falling test masses (TMs) on board interferometers for the detection of gravitational waves in space. The charging process induces spurious forces on the test masses that… read more here.

DOI: 10.1103/physreve.103.032903
Abstract: We study the packing fraction of clusters in free-falling streams of spherical and irregularly shaped particles using flash x-ray radiography. The estimated packing fraction of clusters is low enough to correspond to coordination numbers less… read more here.

DOI: 10.1103/physrevlett.125.064504
Abstract: We present a sweep-stick mechanism for heavy particles transported by a turbulent flow under the action of gravity. Direct numerical simulations show that these particles preferentially explore regions of the flow with close to zero… read more here.
