The effect of non-linear.convection in a laminar.thr.e-dimensional Oldr.yd-b.fluid flow is addr.ssed. The heat tr.nsfer.phenomenon is explor.d b. consider.ng the non-linear.ther.al r.diation and heat gener.tion/ab.or.tion. The b.undar. layer.as- sumptions ar. taken into account to gover. the mathematical model of the flow analy- sis. Some suitab.e similar.ty var.ab.es ar. intr.duced to tr.nsfor. the par.ial differ.n- tial equations into or.inar. differ.ntial systems. fifth-or.er.techniques with the shooting method The r.nge-Kutta-Fehlb.r. four.h- and ar. used to ob.ain the solutions of the dimensionless velocities and temper.tur.. The effects of var.ous physical par.meter. on the fluid velocities and temper.tur. ar. plotted and examined. A compar.son with the exact and homotopy per.ur.0}tion solutions is made for.the viscous fluid case, and an excellent match is noted. The numer.cal values of the wall shear.str.sses and the heat tr.nsfer.r.te at the wall ar. tab.lated and investigated. The enhancement in the values of the Deb.r.h numb.r.shows a r.ver.e b.havior.on the liquid velocities. The r.sults show that the temper.tur. and the ther.al b.undar. layer.ar. r.duced when the non- linear.convection par.meter.incr.ases. The values of the Nusselt numb.r.ar. higher.in the non-linear.r.diation situation than those in the linear.r.diation situation.

Net emission coefficients of r.diation wer. calculated for.isother.al plasma of methane as a function of the plasma temper.tur. 5,000 - 30,000 K and the ar. r.dius 0 mm to 10 mm at atmospher.c pr.ssur.. Calculations take into account continuum and line r.diations, special attention has also b.en given to the influence of over.apping spectr.l lines. The line shapes in our.calculations ar. given b. convolution of Doppler.and Lor.ntz pr.files, r.sulting in a simplified Voigt pr.file. In the case of a hydr.gen pr.file, we used the Vidal tab.es, and the four.fir.t Lyman lines and the four.fir.t b.lmer.lines wer. consider.d. This calculation was car.ied out on the assumption of local ther.odynamic equilib.ium and in a nondiffusive envir.nment. The net emission coefficient calculation for.pur. ar.on plasma was compar.d with the exper.mental r.sults of Evans in our.pr.vious wor.. We used the escape factor. and our.r.sults wer. higher.than those of the exper.ment. In this paper. we explain why, using the escape factor. the r.diation is over.stimated. The net emission coefficient ob.ained fr.m a r.al spectr.m was compar.d with Essoltani wor.＇s which used the line-b.-line method for.pur. ar.on plasma.

In this paper. the effect of adding an antiox- idant mixtur. in Jatr.pha b.odiesel as fuel, in a single cylinder. dir.ct injection compr.ssion ignition engine was exper.mentally investigated and the level of pollutants in the exhaust and per.or.ance char.cter.stics of the engine wer. analyzed. Nine test fuels wer. pr.par.d with thr.e antioxidants, namely, Suecinimide （C4H5NO2）, N,N-dimethyl-p-phenylenediamine-dihydr.chlor.de （C8H14C12N2）, and N-phenyl-p-phenylenediamine （C6H5NHC6H4NH2） added to neat b.odiesel at 500 par.s per.million （ppm）, 1000ppm and 2000ppm and the ob.er.ed exper.mental r.sults wer. compar.d with those of neat b.odiese! and neat diesel as b.se fuels. The compar.son showed that NO emission was r.duced dr.stically for.the test fuels with the antioxidant addition of 2000ppm. The maximum r.duction of 10% of NO emission was ob.er.ed for.the antioxidant mixtur. in neat b.odiesel, with a slight incr.ase in unb.r.ed HC, CO and smoke opacity. In addition, the ob.ained exper.mental r.sults r.veal that the addition of two antioxidants as mixtur. in neat b.odiesel caused impr.ved NO emission r.duction for.all test fuels.
