Computational Fluid Dynamics and Thermal Analysis to Estimate the Skin Temperature of Cockpit Surface in Various Flight Profiles

Optimised Cockpit Heat Load Analysis using Skin Temperature Predicted by CFD and Validation by Thermal Mapping to Improve the Performance of Fighter Aircraft

“…As per our previous research by Gupta 1 , et al, at 313 K ambient temperature and 0.8 Mach No, the theoretical skin temperatures have been calculated as: T skin = 353.064 K (adiabatic heating due to stagnation of fluid) = 337.708 K (heating effect due to viscous dissipation using constant property heat transfer equation at reference temperature T* as reported by Eckert 2 ).…”

“…it is difficult to obtain the first/ second decimal place precision using thermal crayons due to their limitation of measurement accuracy but it gives a fair idea of comparative results of CFD analysis and flight tests. The average cockpit surface temperature obtained from flight tests was compared with CFD and theoretical results of our previous research 1 . The comparison of skin temperature predicted by CFD and theoretically shown in Table 3.…”

CFD-Based Evaluation of Flow and Temperature Characteristics of Airflow in an Aircraft Cockpit

“…In general, flows in cockpits are in a low-speed turbulent state, and experimental data are obtained with high measurement accuracy. For the investigation of airflow features, tests have been performed to characterize the airflow distribution [9][10][11], flow characteristics [12][13][14], and temperature characteristics [13,15,16]. During the airflow transport, the temperature distribution has also been evaluated.…”
