Instability of an active fluid jet [PDF]
arXiv, 2022 The breakup of a fluid jet into droplets has long fascinated natural scientists, with early research dating back to the 19th century. Infinitesimal perturbations to a jet grow because of surface tension, which eventually leads to breakup of the jet into droplets (Rayleigh-Plateau instability).

Falling Jets of Particles in Viscous Fluids [PDF]
Physics of Fluids, 2008 This fluid dynamics video presents experiments and simulations of gravity-driven particulate jets in viscous fluids at low Reynolds number. An initially straight jet is shown to develop varicose modulations of its diameter as it sediments under the action of gravity.

Emission of Low Momentum Particles at Large Angles from Jet [PDF]
, 2012 We study dynamics of a QGP fluid induced by energetic partons propagating through it. We construct a (3+1)-dimensional QGP-fluid+Jet model. When a jet traverses a uniform fluid, it induces a Mach cone structure of energy density distribution and a vortex ring surrounding a path of the jet. When a pair of jets travels through a radially expanding fluid,

Laminar planar jets of elastoviscoplastic fluids [PDF]
arXivWe perform numerical simulations of planar jets of elastoviscoplastic (EVP) fluid (\citet{saramito2007new} model) at low Reynolds number. Three different configurations are considered: $(i)$ EVP jet in EVP ambient fluid, $(ii)$ EVP jet in Newtonian ambient fluid (miscible), and $(iii)$ EVP jet in Newtonian ambient fluid (immiscible). We investigate the

Jet mixing of fluids in tanks.
JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 1982 An experimental investigation was made of the mixing of liquids in a tank where the liquid jet was injected through a nozzle. The mixing time was defined as the time required to reduce the concentration variation within 1% of the mixed mean value and was measured by an impulse response. The circulation time was also obtained from the response curve. It

Control of a Circular Jet [PDF]
arXiv, 2010 The present study report direct numerical simulation (DNS) of a circular jet and the effect of a large scale perturbation at the jet inlet. The perturbation is used to control the jet for increased spreading. Dual-mode perturbation is obtained by combining an axisymmetric excitation with the helical.

Evaluation of a Jet-Pump for the Improvement of Oil-Water Flow in Pipeline Loops Using CFD Tools [PDF]
E3S Web of Conferences, 2021 Despite their low efficiency compared with centrifugal pumps, jet pumps are highly reliable, robust equipment with modest maintenance, ideal for many applications, mainly in the oil & gas industry.

Study on the Characteristics of Coherent Supersonic Jet with Superheated Steam
Metals, 2022 By establishing a mathematical model to simulate a mixed jet of oxygen and superheated steam from a coherent supersonic jet oxygen lance, we studied the effect of superheated steam on the fluid characteristics of the mixed jet.
