We consider the bremsstrahlung energy loss of high energy partons moving in the quarkgluon plasma, at weak coupling. We show that the rates for these processes receive large O(g) corrections from classical (nonabelian) plasma physics effects, which are calculated. In the high-energy (deep LPM) regime these corrections can be absorbed in a change of the transverse momentum broadening coefficient...

The term plasma actuator refers to an asymmetric arrangement of two electrodes (typically rectangular strips) separated by dielectric material that can be used as active flow control devices. A plasma actuator design consisting of an annular electrode array, the plasma synthetic jet actuator (PSJA), is experimentally investigated in this paper. This particular geometry creates a zero-net mass f...

Plasma jets produced by direct-current (dc) non-transferred arc plasma torches, at the core of technologies ranging from spray coating to pyrolysis, present intricate dynamics due to the coupled interaction of fluid flow, thermal and electromagnetic phenomena. The flow dynamics from an arc discharge plasma jet are investigated using time-dependent three-dimensional simulations encompassing the ...

electronic effects were investigated on the singlet–triplet energy gaps of divalent unsaturated seven- membered ring r2c6h6m (m=c, si, ge, sn, pb, r= –h, -ch3, i-pr , t-bu) at b3lyp/6-311++g** level. all the triplet states of r2c6h6c were more stable than the related the singlet states while all the singlet states of r2c6h6m (m= si, ge, sn, pb, r= –h, -ch3, i-pr , t-bu) were more stable than th...

The Interface Region Imaging Spectrograph(IRIS) with its high spatial and temporal resolution brings exceptional plasma diagnostics of solar chromospheric coronal activity during magnetic reconnection. aim this work is to study the fine structure dynamics at a jet base forming mini flare between two emerging fluxes (EMFs) observed IRIS Solar Dynamics Observatory (SDO) instruments. We proceed sp...

We developed a zero-dimensional semi-empirical model to describe the gas phase kinetics in an argon plasma jet flowing into humid air. The model includes an extended plasma chemistry set of 84 different species and 1885 reactions. The density profiles of the biomedically active species are presented for a typical plasma jet device, and the effects of O2, N2 or H2O admixtures to the argon feed g...

Flowing low temperature atmospheric pressure plasma devices have been used in many technological applications ranging from energy efficient combustion through to wound healing and cancer therapy. The generation of the plasma causes a sudden onset of turbulence in the inhomogeneous axisymmetric jet flow downstream of the plasma plume. The mean turbulent velocity fields are shown to be self-simil...

Magnetic fields lines are trapped in black hole event horizons by accreting plasma. If the field lightly loaded with plasma, then their motion is controlled footpoints on horizon and thus spin of hole. In this paper, we investigate boundary layer between polar a dense, equatorial accretion flow. We present an analytic model for aligned prograde retrograde systems argue that there significant sh...
