The article presents details of a URANS simulation of the flow field near a hovering model of the Caradonna and Tung Holders (1981) helicopter rotor [1].The CFD code SPARC [2] proves to be capable of capturing the aerodynamics of a two -bladed rotor in high-speed transonic hover conditions.A comparison of the simulation results with the experimenta
The importance of developing the natural gas liquefaction industry in the Russian Federation is caused by political and economic reasons.In contrast to pipeline export gas supply, when Russia gets into serious dependence on transit countries and countries consuming gas liquefied natural gas (LNG) provides an opportunity to manoeuvre volumes and dir
In this research, the specification of 3-dimensional flow stagnation point of hybrid Nanofluids passing through circular cylinder with sinusoidal radius are analyzed.C2H6O2, H2O and Engine oil are used as an ordinary liquid, while nano-particles include SWCNT and MWCNT.Fluid stream is taken into account with/without considering the effect of therma
