Study of Interaction between Unsteady Supersonic Jet and Shock Waves in Elliptical Cell
Journal of Fluid Science and Technology, 2008 The unsteady behavior of a flow driven by a jet suddenly injected into cells is investigated numerically by solving the axisymmetric two-dimensional compressible Navier-Stokes equations.

Study of diffusion control in circular jet using concentric-type DBD plasma actuator
Journal of Fluid Science and Technology, 2014 An investigation was carried out into diffusion control for a circular jet using a concentric dielectric barrier discharge plasma actuator, focusing on the effects of electrode size, driving frequency and applied voltage. The actuator was found to induce

Observation of eruptive events with the Siberian Radioheliograph
Solar-Terrestrial Physics, 2018 We describe methods for monitoring eruption activity with the first phase of the multiwave Siberian Radioheliograph (SRH-48). We give examples of the recorded eruptive events: 1) rise of a prominence above the limb observed in the radio map sequence of ...

Journal of Fluid Science and Technology, 2023 In the present study, the influence of the direction of the backward plasma-induced flow generated by a plasma actuator (PA) on the jet flow was investigated. In the case of the backflow PA, the centerline velocity was increased by the contraction of the

Jet reconstruction and jet properties at HERA
Zeitschrift für Physik C Particles and Fields, 1988 We discuss jet reconstruction methods with respect to their suitability forep collisions at HERA and study the expected properties of such jets. The results are based on complete event simulation using current models of jet evolution and hadronization in combination with experimentally tested jet algorithms.
