#+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ # # HLPW-4 Iterative Convergence for CLmax Study in Wind Tunnel DATA SUBMITTAL FORM Case 2b (Version 2), January 13, 2021 # # CASE 2b is a study of the HL-CRM nominal 40/37 configuration near CLmax. # REQUIRED: Please report results on your best (finest) mesh; the same mesh "level" should be used for all cases. # OPTIONAL: Include results on other mesh levels if you have them. # For RANS, this case should be run FULLY TURBULENT (no forced transition) WITH WIND TUNNEL WALLS. # # NOMENCLATURE: # N: Number of unknowns (grid points for node-centered code, grid cells for cell-centered code) # ITER: Iteration or time step number (ITER1=first recorded time step, ITERn=last time step). # ITERn-ITER1 should be long enough to show any range in variation of final forces and moments. # If no variation exists (i.e., steady-state reached), provide at least the final 25% of the # range of iterations used. # TIME: if run time-accurately, this is the corresponding nondimensional time since you started # the computation (t*U_freestream/MAC) # CL: Coefficient of lift (total) # CD: Coefficient of drag (total) # CM: Coefficient of pitching moment (CMy) about moment reference center (MRC) (total) # RESIDM-n: (Optional) Residual of selected mean-flow equation (n=equation number) # RESIDT-n: (Optional) Residual of selected turbulence equation (n=equation number) # # MAC: Mean aerodynamic chord = 275.8 inches # FT: Fully Turbulent # WT: Wind Tunnel # # XXX: Participant ID (To be assigned by HLPW committee) # # FLOW CONDITIONS: # Angles of Attack: 1.99, 5.98, 9.98, 15.48, 17.98, 18.97, 19.98 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. Please use scientific notation (e.g. 2.51e-6) in the numerical values for RESIDM-n and RESIDT-n # 4. Residuals are optional; as many residuals can be provided as desired (up to 5 for mean flow, # up to 7 for turbulence) # 5. If data are NOT provided, please fill data fields with a numerical value of "-999" # 6. Indicate (using each DATASETAUXDATA) whether local-time-stepping or time-accurate method was used # 7. You may include additional angles of attack in addition to those specified, if desired # #+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ TITLE = "XXX" # <------------------------------------------------------------ OPTIONAL -----------------------------------------------------------> VARIABLES = "N" "ITER" "TIME" "CL" "CD" "CM" "RESIDM-1" "RESIDM-2" "RESIDM-3" "RESIDM-4" "RESIDM-5" "RESIDT-1" "RESIDT-2" "RESIDT-3" "RESIDT-4" "RESIDT-5" "RESIDT-6" "RESIDT-7" DATASETAUXDATA TIMESTEPPING_METHOD_1p99 = "local-time-stepping -or- time-accurate" ZONE T="XXX case2b alpha=1.99 WT FT" -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 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 -999 # etc...
