15 صفحه اولNumerical Simulation of Mixing Enhancement in a Hot Supersonic Jet
Experimental observations show that the presence of small tabs on the edge of a hot, compressible jet exiting into a slower moving, colder ambient ow can increase the rate of spreading of the jet. This suggests that the rate of mixing of the jet and the ambient uid is also increased. In order to elucidate the physical mechanism responsible for the increased spreading rate a set of calculations ...
متن کاملDirect Numerical Simulation of a Sonic Round Jet in a Turbulent Supersonic Cross Flow
A direct numerical simulation of a round under-expanded sonic jet in turbulent supersonic cross flow has been carried out. The objective is to investigate the mixing mechanism which occurs downstream the jet by use of a passive scalar variable. The Navier-Stokes equations in the cylindrical geometry are solved by use of multiblock overlapping meshes. The method has been validated with a laminar...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
