Table 5. Results of sensitivity analysis for different configurations (AFN-coupled)
"... In PAGE 9: ... The sensitivity in this case is restricted to the convective heat transfer coefficient, as the airflow parameter is dealt with in the AFN. In Table5 the results are shown numerically. Figure 8.... In PAGE 9: ...he airflow parameter is dealt with in the AFN. In Table 5 the results are shown numerically. Figure 8. Results for the investigated performance indicators of the case study (AFN-coupled) Table5 . Results of sensitivity analysis for different configurations (AFN-coupled) Again, at this point in the design process, there are two decisions that should be made, whether a CFD- coupled simulation is needed, and if yes, which configuration(s) should be selected for further simulation.... ..."
Table 6. Results of sensitivity analysis with AFN- coupled simulation for all configurations
"... In PAGE 9: ... Results of sensitivity analysis for different configurations (AFN-coupled) Again, at this point in the design process, there are two decisions that should be made, whether a CFD- coupled simulation is needed, and if yes, which configuration(s) should be selected for further simulation. Therefore in Table6 the results of the sensitivity analysis with the AFN-coupled simulations are compared to the results for the BEB-only simulations. The results are shown for Configurations 1, 4 and 5 respectively.... In PAGE 10: ...10 Table6 . Results of sensitivity analysis with AFN-coupled simulation for all configurations In Table 6 significant differences can be found between the calculated individual performance indicators for the two approaches.... In PAGE 10: ...10 Table 6. Results of sensitivity analysis with AFN-coupled simulation for all configurations In Table6 significant differences can be found between the calculated individual performance indicators for the two approaches. Differences up to a factor five and higher are calculated, especially for the energy related performances.... In PAGE 10: ... At this point, there is however not enough information to support this assumption. Turning back to the results, in Table6 a sensitivity of more than 20% is shaded. Applying this information Configuration 1 and 5 have several cases that would require a CFD-coupled simulation, while this is not required for Configuration 4.... ..."
Table 1: CFD Case Summary
"... In PAGE 4: ... A single forebody CFD solution based upon these free stream conditions was computed and com- bined with various internal nozzle solutions to initialize the aftbody flow field for each solution. Twelve internal nozzle/exhaust combinations were computed using four noncombusting, ther- mally perfect gas mixtures at both cold and hot (combustion) temperatures (see Table1 ). Four cases used air as the exhaust gas, three at cold conditions for a range of NPR values and one hot case at the baseline NPR.... In PAGE 5: ... Each of the internal nozzle solutions was merged with the single forebody solution via bilinear interpolation at the cowl exit plane to initialize each aftbody flow field solution. The cases comprising the study ( Table1 ) were charac- terized by the exhaust gas mixture, jet condi- tions, and a corresponding internal nozzle geometry. Figure 5 shows the relationships between the NPR and SNPR4 for each case.... In PAGE 7: ... Forces and Moments Figure 6 shows longitudinal aftbody force and moment components normalized by the magni- tudes of the forces and moments of the hot scram- jet combustion products simulation, using the (more complete) six-species combustion products mixture at the baseline NPR=3000, plotted ver- sus SNPR4. Each of the simulant exhaust approximations described in Table1 are shown, including the single data point for hot air exhaust. In general, for a given exhaust mixture at a given total temperature the variations with respect to SNPR4 are nearly linear.... ..."
