Laminar sheath gas is introduced to increase the stability of Electrohydrodynamic Direct-Writing (EDW). The external stretching force from promotes ejection threshold, diameter jet and printed fibers as well. critical voltage decreases with pressure. fiber well that charged jet. As pressure increases 0 25 kPa, average micro/nano structure reduces 4.46μm 845.25 nm. laminar field flow shelters free surrounding interferences, helps move in a straight line. With help gas, can be improved...
Abstract Ionic liquid electrospray thrusters with high specific impulse, thrust accuracy and low noise are very promising for space gravitational wave detection missions. The plume, which may lead to surface charging of solar panels sensitive spacecraft components is a great concern the applications thruster. Therefore, this paper investigates plume neutralization process ionic thruster through fully kinetic particle-in-cell simulations. unipolarity operation mode firstly simulated compared...
Rarefication effects on jet impingement loads are studied by comparing recent new formulas at the collisionless flow limit and numerical simulations. The exit size is finite, can be either planar or round. In simulations, jets have different degrees of rarefication, with a Knudsen (Kn) number ranging from 0 to infinity; i.e., flows continuum, collisional, collisionless. comparison results indicate that (1) surface load accurate limit; (2) in general, offer upper limits for peak loads; (3)...
This paper reports the recent development of a full-scale particle-in-cell (PIC) simulation package highlighting an efficient electro-statics (ES)-PIC implementation for spacecraft charging problems. Numerical simulations are crucial in studying plasma flows because analytical solutions rare, and experiments expensive. There many types flow that need various numerical methods accurate simulations; as such, how to implement organize those different into one comprehensive is challenging. work...
Abstract 3D hybrid particle-in-cell simulations were performed to investigate the ion current collection behavior by a thin double-sided circular planar probe in both stationary and parallel flowing plasmas with cold ions Boltzmann electrons. Results for plasma cases showed that assumption of constant density ratio at sheath boundary unperturbed is inaccurate probes radii from 10 30 Debye length biases −5 −30 times electron temperature. The results strongly depends on velocity, contrary...
Temperatures and displacements for all the components of an electron gun with a control grid are computed. The results show thermal stress slightly. obtained deformation data can be helpful to modify design dimensions assembly gun.
This short note presents concise semi-analytical expressions for electron temperature and potential in unsteady dilute cold plasma flows. The analysis is based on the detailed fluid model electrons. Ionizations normalized number density gradients are neglected, transport properties assumed as local constants. Flow Maxwell's equations adopted analysis. With these treatments, partial differential degenerate ordinary equations. Along an streamline, two simple formulas obtained. These offer some...
Low pressure oscillating water flow can reduce the investment and energy consumption of irrigation. It is also effective in reducing clogging an emitter improving spraying quality sprinklers. In order to overcome problem complex process calculating amplitude head loss different types pipes, this study, empirical equation for pipe has been developed. Further, validation experiments have conducted verify accuracy calculated amplitudes by equation. The results show that average relative error...
