#+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ # # HLPW-4 Force/Moment Grid Convergence DATA SUBMITTAL FORM Case 1b (Version 2), January 13, 2021 # # CASE 1b is a mesh convergence study for the HL-CRM nominal 40/37 configuration at alpha=7.05 deg. # For RANS, this case should be run FULLY TURBULENT (no forced transition) in FREE AIR (no tunnel walls). # # NOMENCLATURE: # N: Number of unknowns (grid points for node-centered code, grid cells for cell-centered code) # CL: Coefficient of lift (total) - give mean if not converged to steady-state # CD: Coefficient of drag (total) - give mean if not converged to steady-state # CM: Coefficient of pitching moment (CMy) about moment reference center (MRC) (total) # - give mean if not 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) # TSTART: if run time-accurately and averaged in time, this is the starting time when time-averaging # began = (time after run initiation)*U_freestream/MAC # TAVG: if run time-accurately and averaged in time, this is the averaging time = # (averaging time)*U_freestream/MAC # # MAC: Mean aerodynamic chord = 275.8 inches # FT: Fully Turbulent # # XXX: Participant ID (To be assigned by HLPW committee) # # FLOW CONDITIONS: # Angle of Attack: 7.05 deg # Mach Number: 0.2 # Reynolds Number: 5.49 million (based on MAC) # Freestream Temp: 521 R # Freestream Static Pressure: 24.67 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 data are NOT provided, please fill data fields with a numerical value of "-999" # 4. If not converged to steady-state (i.e., if run with a scale-resolving simulation # or run time-accurately), give mean values of CL, CD, and CM # #+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ TITLE = "XXX" VARIABLES = "N" "CL" "CD" "CM" "DT" "TSTART" "TAVG" ZONE T="XXX case1b ALPHA=7.05 freeair FT" # Supply as many lines as grid levels run (e.g, level A, B, ... , F: -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999
