Pipes are used all over the world for the basic utility of transfer of small solids, gases, slurries and liquids. Sometimes the term pipes and tubes is interchangeably used, the difference remains. The cross-sectional variations of these flow components results in the variation of characteristics under pressurized conditions. In the manufacturing of bend pipes the control over the outer diameter is quiet easily possible, but the inner diameter variations can be expected. At the bend, the thinning of the exterior part of the bend and the thickening of the interior part is seen. In the subsequent study the comparative flow analysis of the bend pipe of a circular cross-section and the oval pipe is analyzed. The characteristics flow velocity change, turbulence induced, density and pressure variations, temperature change in its course are focused. ANSYS FLUENT is used for the analysis of a standalone pipe of specified dimensions. © 2017 Published under licence by IOP Publishing Ltd.
