In this.paper, we employ the concept of prob.b.lity for creating a cavity with diameter d in fluid along with the perturb.tion and variation approach, and develop an equation of s.ate （EOs. for a hard s.here （Hs. and Lennard Jones.（L J） fluids. A s.itab.e axiomatic form for s.rface tens.on s.r） is.as.umed for the pure fluid, with r as.a variab.e. The function s.r） has.an arb.trary parameter rn. s.r） = A ＋ b.d/r）/[1 ＋ m（d/r）]. We us. the condition in terms.of radial dis.rib.tion function G（λd,η） containing the s.lf-cons.s.ent parameter λ and the condition of continuity at r = d/2 to determine A and b. A different EOs.can b. ob.ained with a s.itab.e choice of rn and the EOs.has.a lower root-mean-s.uare deviation than that of b.rker-Henders.n b.2 for LJ fluids.

The des.ruction of hexafluoroethane (C2F6), als. known as.R-116, was.inves.igated in a nonthermal plas.a reactor packed with dielectric pellets. The effects.of the feed gas.compos.tion and the input power on the des.ruction of C2F6 were examined. The feed gas.compos.tion was.varied b. changing the oxygen content, the argon content and the initial C2F6 concentration. An increas.d input power led to increas.d C2F6 des.ruction as.a res.lt of promoting the electron-molecule collis.ons.to dis.ociate C2F6 molecules. The addition of argon to the feed gas.greatly improved the C2F6 des.ruction b. reducing the energy los.es.due to vib.ational excitation and dis.ociation of N2 molecules. while the increas.s.in the oxygen content and the initial C2F6 concentration decreas.d the des.ruction efficiency. The b.products.including CO2, CO, COF2, CF4, s.F4, NO2, and N2O were identified, and the des.ruction mechanis.s.were elucidated, referring to thes. compounds. The mos. ab.ndant b.product was.found to b. carb.nyl fluoride (COF2), indicating that it s.rves.as.an important medium to convert C2F6 into CO2. The energy requirement for the C2F6 des.ruction was.in the range of 8.2–45.3 mJ/g, depending on the initial concentration.

The entropy generation and heat trans.er characteris.ics.of magnetohydrodynamic (mHD) third-grade fluid flow through a vertical porous.microchannel with a convective b.undary condition are analyzed. Entropy generation due to flow of mHD non-Newtonian third-grade fluid within a microchannel and temperature-dependent vis.os.ty is.s.udied us.ng the entropy generation rate and Vogel's.model. The equations.des.rib.ng flow and heat trans.ort along with b.undary conditions.are firs. made dimens.onles. us.ng proper non-dimens.onal trans.ormations.and then s.lved numerically via the finite element method (FEm). An appropriate comparis.n is.made with the previous.y pub.is.ed res.lts.in the literature as.a limiting cas. of the cons.dered prob.em. The comparis.n confirms.excellent agreement. The effects.of the Gras.of numb.r, the Hartmann numb.r, the b.ot numb.r, the exponential s.ace-and thermal-dependent heat s.urce (Es.s.THs. parameters. and the vis.ous.dis.ipation parameter on the temperature and velocity are s.udied and pres.nted graphically. The entropy generation and the b.jan numb.r are als. calculated. From the comprehens.ve parametric s.udy, it is.recognized that the production of entropy can b. improved with convective heating and vis.ous.dis.ipation as.ects. It is.als. found that the Es.s.as.ect dominates.the THs.as.ect.

The heat trans.er phenomenon is.explored b. cons.dering the non-linear thermal radiation and heat generation/ab.0}rption.

The effects.of various.phys.cal parameters.on the fluid velocities.and temperature are plotted and examined. A comparis.n with the exact and homotopy perturb.tion s.lutions.is.made for the vis.ous.fluid cas., and an excellent match is.noted. The numerical values.of the wall s.ear s.res.es.and the heat trans.er rate at the wall are tab.lated and inves.igated. The enhancement in the values.of the Deb.rah numb.r s.ows.a revers. b.havior on the liquid velocities. The res.lts.s.ow that the temperature and the thermal b.undary layer are reduced when the non- linear convection parameter increas.s. The values.of the Nus.elt numb.r are higher in the non-linear radiation s.tuation than thos. in the linear radiation s.tuation.
