Beating the jetting regime
We study numerically the dynamics of jets and drops in a microcapillary coflow device. The co-flow stream encounters different flow regimes, including dripping, jetting. Using a level-set/finite element axysimmetric numerical simulation, we study the dynamics of breakup of a jet subject to flow rate perturbations. A scaling law for the width of the unperturbed jet is presented and compared to e...
متن کاملTwo-phase viscoelastic jetting
A coupled finite difference algorithm on rectangular grids is developed for viscoelastic ink ejection simulations. The ink is modeled by the Oldroyd-B viscoelastic fluid model. The coupled algorithm seamlessly incorporates several things: (1) a coupled level set-projection method for incompressible immiscible two-phase fluid flows; (2) a higher-order Godunov type algorithm for the convection te...
متن کاملSonoporation from jetting cavitation bubbles.
The fluid dynamic interaction of cavitation bubbles with adherent cells on a substrate is experimentally investigated. We find that the nonspherical collapse of bubbles near to the boundary is responsible for cell detachment. High-speed photography reveals that a wall bounded flow leads to the detachment of cells. Cells at the edge of the circular area of detachment are found to be permanently ...
متن کاملBeating the Standard Model *
Although our beloved standard model of quarks and leptons offers a complete, consistent and correct description of most particle phenomena, lots of vexing questions remain unanswered, such as: Why are the gauge group and the fermion masses what they are? Why three families of quarks and leptons? What breaks electroweak symmetry? How about gravity? Leaving such profound meta-questions to supersy...
متن کاملBeating the Pink
Introduction: Kaposi sarcoma (KS) is an HIV associated skin lesion. Kaposi sarcoma is rare in HIV negative patients and is associated with HHV-8 infection. Clinically it presents as a pink nodular mass, single or multiple which can mimic pyogenic granuloma and bacillary angiomatosis. The etiology associated with HHV-8. Treatment options modalities can vary between from electrocuatery to surgica...
