Experimental Study of Fluid Jet Mixing at Supercritical Conditions

, 2010
Subcritical and supercritical fluids were injected in an inert gaseous atmosphere. Density distribution was measured and density-gradient profiles were inferred from the experimental data.

The wall jet in a rotating fluid

Journal of Fluid Mechanics, 1997
The previously observed spatial evolution of the two-dimensional turbulent flow from a source on the vertical wall of a shallow layer of rapidly rotating fluid is strikingly different from the non-rotating three-dimensional counterpart, insofar as the instability eddies generated in the former case cause the flow to separate completely from the

Two-fluid jets and wakes

Physics of Fluids, 2004
Similarity solutions for laminar two-fluid jets and wakes are derived in the boundary-layer approximation. Planar and axisymmetric fan jets as well as classical and momentumless planar wakes are considered. The interface between the immiscible fluids is stabilized by the action of gravity, with the heavier fluid, taken to be a liquid, placed beneath ...

Stability of a magnetic fluid jet

International Journal of Engineering Science, 1991
Abstract The stability of a magnetic fluid jet in the presence of a magnetic field when the field is either azimuthal or axial is investigated by using the energy principle. By constructing the respective Lagrangian functions and solving the associated Euler-Lagrange equations of motion, the dispersion relations are derived.

The steady cone-jet mode of electrospraying close to the minimum volume stability limit

Journal of Fluid Mechanics, 2018
We study both numerically and experimentally the steady cone-jet mode of electrospraying close to the stability limit of minimum flow rate. The leaky dielectric model is solved for arbitrary values of the relative permittivity and the electrohydrodynamic

Electrospinning: A whipping fluid jet generates submicron polymer fibers

, 2001
Polymeric fibers with diameters in the range from 50 nm to 5 μm are produced by accelerating a fluid jet in an electric field, in a process known as “electrospinning.” Here we show that an essential element of the process is a fluid instability, the ...

Modeling and Computational Fluid Dynamics−Population Balance Equation−Micromixing Simulation of Impinging Jet Crystallizers

, 2009
Computational fluid dynamics (CFD), micromixing modeling, and the population balance equation (PBE) are coupled to simulate the crystal size distribution in a confined impinging jet crystallizer.

Edge effect in fluid jet polishing

Applied Optics, 2006
The edge effect is one of the most important subjects in optical manufacturing. The removal function at different positions of the sample in the process of fluid jet polishing (FJP) is investigated in the experiments. Furthermore, by using finite-element analysis (FEA), the distributions for velocity and pressure of slurry jets are simulated ...
