Turbulence grids are placed in the shock tube to generate shock induced turbulence in the wake of the grid plate. All turbulent fluctuations are computed along the longitudinal distance in the wake of the grid plate in the shock tube and it is observed that the decay of the turbulence and the decay of Turbulence Kinetic Energy (TKE) level are accelerated along the downstream direction and the percentage of decay depends on the strength of incident shock wave. Due to stronger compressibility effects on decaying turbulent field, all length scales are decreased along the downstream direction. The decay of dissipation rate of TKE is observed along the downstream direction for gradually decreasing the turbulence intensity in the wake of the grid plate. 2014-08-19T04:23:51Z 2014-08-19T04:23:51Z 2014-06 Other The Journal of the Institution of Engineers, Malaysia, vol. 75(1), 2014, pages 40-48 0126-513X http://dspace.unimap.edu.my:80/dspace/handle/123456789/36827 en The Institution of Engineers, Malaysia (IEM)
