Synthetic synchrotron emission maps from MHD models for the jet of M87

, 2009
We present self-consistent global, steady-state MHD models and synthetic optically thin synchrotron emission maps for the jet of M87. The model consist of two distinct zones: an inner relativistic outflow, which we identify with the observed jet, and an ...

The Evolution of Hetergeneous "Clumpy Jets": A Parameter Study

, 2011
We investigate the role discrete clumps embedded in an astrophysical jet play on the jet's morphology and line emission characteristics. By varying clumps' size, density, position, and velocity, we cover a range of parameter space motivated by ...

Computational Study on Effect of Synthetic Jet Design Parameters

International Journal of Aerospace Engineering, 2010
Effects of amplitude and frequency of synthetic jet on the characteristics of induced jet are investigated. To estimate effects of the parameters, flow inside the synthetic jet cavity and orifice and the outer flow is simultaneously simulated using large-

Shaping point- and mirror-symmetric proto-planetary nebulae by the orbital motion of the central binary system

, 2009
We present 3D hydrodynamical simulations of a jet launched from the secondary star of a binary system inside a proto-planetary nebula. The secondary star moves around the primary in a close eccentric orbit.

Optimization of Synthetic Jet Position for Heat Transfer Enhancement and Temperature Uniformity of a Heated Wall in Micro-Channels

Journal of Applied Fluid Mechanics, 2019
In this study, the synthetic jet position was optimized to obtain the maximum rate of heat transfer and the best state of temperature uniformity on a heated surface in micro-channels.

A study on backward facing step flow in low Reynolds number manipulated by synthetic jets - Effect of different jet velocities -

Journal of Fluid Science and Technology, 2014
This study presents the detailed structure of separated flow downstream of a backward facing step affected by a non-uniform periodic disturbance along spanwise direction induced by a synthetic jet array.

Comparison of synthetic maps from truncated jet-formation models with YSO jet observations [PDF]

, 2010
(abridged) Significant progress has been made in the last years in the understanding of the jet formation mechanism through a combination of numerical simulations and analytical MHD models for outflows characterized by the symmetry of self-similarity. In

Development of A Compact Synthetic Jet Generator Driven by Electromagnetic Micro Flap Actuator

Journal of Fluid Science and Technology, 2011
In this study, a compact synthetic jet generator using electromagnetic micro flap actuator as a driving mechanism is developed and tested. Firstly, the effects of flap's width and length on static and dynamic responses of the driving mechanism are ...
