The flow and heat transfer mechanisms of mist/air film cooling are studied in this paper with three hole types under blowing ratios. velocity vectors three-dimensional contours the vortices shown order to investigate characters different types. Both span averaged centerline effectiveness compare performance types.Mist/air performances cylindrical hole, fan-shaped console numerically. Flow structures jets studied. Results show that kidney vortex uplifts mists further away from flat plate...
Damage-modified nonlinear viscoelastic constitutive equation and failure criterion are introduced the three-dimensional incremental forms deduced based on updated Lagrangian approach. A simple tensile test model a split Hopkinson pressure bar built to verify accuracy of subroutine implemented within non-linear finite element program LS-DYNA. numerical bird strike windshield is established study responses under three different velocities at sites. The represented by cylinder with hemisphere...
In order to increase entry gas temperature and improve the efficiency of turbine, steam is used as a coolant instead air. Much research has been carried out on closed circuit cooling vanes substituted with film-cooling using compressor air in recent years. Furthermore, by studying flow heat transfer characteristics rib ducts, this investigation focuses establishing basis technology application complex field internally-cooled turbine vane. paper, report assessment RSM method based SSG...
In order to further study the effects of target channel shape on cooling performance double swirl (DSC), five channels formed by two overlapping elliptic cylinders with different length ratio between vertical semi-axis and horizontal are applied. Numerical studies carried out under three Reynolds numbers. The flow characteristics heat transfer DSC cases compared benchmark impingement case. losses, cross-flow development, generated vortices, velocity distributions inside illustrated,...
A double swirl cooling method has been raised recently to enhance the internal performance at blade leading edge. This paper mainly focuses on investigating flow and heat transfer characteristics of method. Further more, four kinds elliptical holes are applied show effects impinging hole shapes performance. Results all cases compared with that an impingement structure under Reynolds numbers. Overall averaged Nusselt number, friction factor thermal in cases, Vortexes induced by different...
In a direct-transfer pre-swirl system, cooling air expands through stationary nozzles and flows the cavity to receiver holes located in rotating turbine disc for blade cooling. This paper investigates effect of length-to-diameter ratios on performance system rotor-stator cavity. The commercial code CFX 12.1 is used solve Reynolds-averaged Navier–Stokes equations using SST turbulence model. Computations are performed seven ratios, L/ D = 1, 2, 3, 4, 5, 6, 7, range 0.5 < β p <2.0,...
