Szukana fraza: [Abstract = "Five converging\-diverging or diverging\-converging geometrics, viz. wedge and cone, parabolic, hyperbolic, hyperbolic cosine and cosine curve, are used as examples to illustrate the application of this method. For the wedge and cone geometry the present results for the power\-law fluid were compared with the results obtained by another method\; this comparison indicates a good compatibility between both the results."]
