the effect of addition of qodumeh shahri (lepidium perfoliatum) seed gum on the emulsion properties were investigated in this study. l. perfoliatum seed gum with 0-0.6% (w/w) concentration was used together with 2% (w/w) wpc to emulsify 20% (w/w) corn oil. the emulsion was analyzed for emulsion stability, particle size, specific surface area, particle size distribution and rheological propertie...

Motivated by capture and detection of airborne biological agents in real time with a cantilever biosensor without introducing the agents into liquids, we present the effects of inlet/outlet configurations of a homemade particle collector on the electrostatic capture of airborne 100 nm diameter nanoparticles under swirling gas flows. This particle collector has three different inlet/outlet confi...

The Coarse-Graining Procedure (CGP) (Y. Chen and S. E. Parker, Physics of Plasmas 14, 082301 (2007)) is implemented in the GEM code for electrons. While CGP introduces numerical dissipation in the particle-in-cell (PIC) simulations, it is shown that CGP preserves physical dissipation effects such as the electron-ion collisional effects on the particle flux in Ion-Temperature-Gradient (ITG) driv...

The ion drag force on a spherical dust particle immersed in a flowing plasma with an external electric field is self-consistently calculated using the particle-in-cell code SCEPTIC in the entire range of charge-exchange collisionality. Our results, not based on questionable approximations, extend prior analytic calculations valid only in a few limiting regimes. Particular attention is given to ...

We have undertaken simulations of steady-state multiphase flows using the Lagrangian technique. It was noted that in previous studies, we found simulations for certain numerical parameters, flow conditions and problems, that it was not possible to achieve a high-order convergence for the residuals. In this paper we discuss some of these problems and attempt to solve them by various techniques. ...
