In a previous paper (McGroarty & Ray, 2004) we examined the environment of a number of evolved low -mass young stars, i.e. Classical T Tauri Stars, to see if they are capable of driving parsec scale outflows. These stars CW Tau, DG Tau, DO Tau, HV Tau C and RW Aur were previously known to drive only “micro jets” or small scale outflows of ≤ 1′ or 0.04 pc at the distance of the Taurus Auriga Clo...

This paper aims to understand how a micro synthetic jet actuator works effectively to prevent the boundary layer flow from laminar separation aused by adverse pressure gradient. Experimental results showed that synthetic jets were effective when the forcing frequency was a lower frequency f the Tollmien–Schlichting (T–S) wave, which received amplification from the base flow. They demonstrated t...

By using molecular dynamics, we have investigated the effect of nanoscale helium (He) bubbles on formation micro-jets and various physical mechanisms under supported unsupported shock wave loading. Our simulations suggest that micro-jet is primarily influenced by local dynamics nano-He bubbles, as velocity in copper–helium (Cu–He) system slightly slower than pure Cu. The expansion He can accele...

Designing and manufacturing the multiple jets simulator and experimental investigation of the multiple jets in crossflow at low velocity ratios have been studied Together with design and build a low-speed wind tunnel. A specific rake is used to determine the flow field pressure and changes in static pressure measured by pressure taps in the near field of the jets. There are generally three regi...

We analyzed simultaneous extreme-ultraviolet (EUV) data from the Transition Region and Coronal Explorer (TRACE) and H data from Big Bear Solar Observatory (BBSO). In the active region studied, we found several EUV jets which repeatedly occurred where pre-existing magnetic ux was \canceled" by newly emerging ux of opposite polarity. The jets look like Yohkoh soft X-ray jets, but are smaller and ...
