#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ # # HiLiftPW-3 Force/Moment Grid Convergence DATA SUBMITTAL FORM Case 1b (Version 1), March 2017 # # CASE 1b is an optional grid convergence study for the HL-CRM configuration, using grid adaptation # Here, "coarse", "medium", and "fine" correspond to grids with successively more adaptation # (the finest adapted grid should be included; participant can include as many levels coarser as appropriate) # Two ALPHAs (8 and 16 deg) are required. # This case should be run FULLY TURBULENT (no forced transition). # # NOMENCLATURE: # ALPHA: Angle of attack, deg. # N: Total number of grid points (node-centered code) or grid cells (cell-centered code) # CL: Coefficient of lift (total) # CD: Coefficient of drag (total) # CM: Coefficient of pitching moment about moment reference center (MRC) (total) # VARCL: Oscillation/variation magnitude in CL (CLmax-CLmin)/2; enter 0 if converged to steady-state # VARCD: Oscillation/variation magnitude in CD (CDmax-CDmin)/2; enter 0 if converged to steady-state # VARCM: Oscillation/variation magnitude in CM (CMmax-CMmin)/2; enter 0 if converged to steady-state # DT: nondimensional time step if run time-accurately (dt*U_freestream/MAC); # enter -1 if run in steady-state mode (non-time-accurately) # # MAC: Mean aerodynamic chord = 275.8 inches # FT: Fully Turbulent # # XXX: Participant ID (To be assigned by HiLiftPW workshop committee) # # FLOW CONDITIONS: # Mach Number: 0.2 # Reynolds Number: 3.26 million (based on MAC) # Freestream Temp: 518.67 R (= 15.0 C = 59.0 F) # Freestream Static Pressure: 760.21 mmHg (= 14.70 psi) # # NOTES: 1. All numerical data fields can be free-formatted # 2. Please use at least 5 decimal places in the numerical values for CL CD CM # 3. If optional data is NOT provided, please fill data fields with a numerical value of "-999" # 4. If not converged to steady-state, give approximate mean values of CL, CD, and CM # along with VARCL, VARCD, and VARCM, such that (e.g.) CL +- VARCL describes the variation # #++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ TITLE = "XXX" VARIABLES = "ALPHA" "N" "CL" "CD" "CM" "VARCL" "VARCD" "VARCM" "DT" ZONE T="XXX case1b ALPHA=8 FT fullgap" # adapted coarse grid (less adaptation): 8.0 -999 -999 -999 -999 -999 -999 -999 -999 # adapted medium grid (more adaptation): 8.0 -999 -999 -999 -999 -999 -999 -999 -999 # adapted fine grid (most adaptation): 8.0 -999 -999 -999 -999 -999 -999 -999 -999 ZONE T="XXX case1b ALPHA=16 FT fullgap" # adapted coarse grid (less adaptation): 16.0 -999 -999 -999 -999 -999 -999 -999 -999 # adapted medium grid (more adaptation): 16.0 -999 -999 -999 -999 -999 -999 -999 -999 # adapted fine grid (most adaptation): 16.0 -999 -999 -999 -999 -999 -999 -999 -999
