************************************************************************ ************************************************************************ DATA FROM DNS OF IMPINGING SHOCK WAVE BOUNDARY LAYER INTERACTION (M = 2.28) 06 / 12 / 2010 ************************************************************************ ************************************************************************ The parameters of the simulation are Free-stream Mach number ====> M = 2.28 Reynolds number based on the inlet BL thickness ====> Re = 16750. Incidence angle of the shock generator ====> phi = 8 degree gamma = 1.4 The file "blinc.dat" is a simple ascii file where mean and velocity fluctuations are reported for a station of the incoming boundary. Data are taken at the station x=43.6 where the main properties are Mach = 2.28 (Mach number) delta* = 0.497 (displacement thickness) theta = 0.140 (momentum thickness) Re_theta = 2344 (Reynolds number based on theta) Re_tau = 466 (friction Reynolds number) H = 3.55 (shape factor) cf = 2.56E-03 (skin friction coefficient) The reference length is the boundary layer thickness at the inlet. The file can be read as ************************************************************** FORTRAN CODE ************************************************************** open(unit=12,file='blinc.dat',form='formatted') do j=1,jj read(12,*) (a(j),l,l=1,12) enddo close (12) ************************************************************** where jj=153 (data are reported up to y/delta99 = 1.2). The array a contains the following variables m variable ------------ 1 y/delta99 2 y+ 3 u 4 uvd+ (Van-Driest transformed mean streamwise velocity) 5 urms (root-mean-square of streamwise velocity fluctuations) 6 vrms (root-mean-square of wall-normal velocity fluctuations) 7 wrms (root-mean-square of spanwise velocity fluctuations) 8 u'v' (shear stress) 9 urms+ 10 vrms+ 11 wrms+ 12 sqrt(rho/rhow) (square root of the ratio between the mean density and the wall density) The reference velocity is taken to be the free-stream values.
