Abstract:The fluid dynamics of circular jet in the near field region is investigated in this paper by the DNS method.The compressible Navier Stokes equations are solved including the continuity, momentum,energy and perfect gas state equations in order to give a clear understanding of the jet development in the near-field region.The Reynolds number is about 5000,and the total grids used in our simulation is about 30 million.The evolution of turbulent properties in the near-field region is presented and analysed expli...
Keywords:circular jet  direct numerical simulation  kinetic energy
