Kriging prediction of L/D based on data from 12 wind-tunnel tests.



Kriging prediction of L/D based on data from 120 VGK simulations (figure 2 caption explains plot).



Co-Kriging prediction of L/D based on data from 120 VGK simulations and 12 wind-tunnel tests (figure 2 caption explains the plot).



Rear-wing design variables.



(a) Hill-climb race-car rear-wing geometry and (b) half-car geometry (which is used for the ‘full-car’ simulations).



Simulated flow over a baseline rear wing in isolation.



Simulated flow over a baseline rear wing behind the full car.



Kriging prediction of L/D based on 20 full-car simulations.



Kriging prediction of L/D based on 120 rear-wing simulations (figure 9 caption explains the plot).



Co-Kriging prediction of L/D based on 10 full-car and 120 rear-wing simulations (figure 9 caption explains the plot).



L/D values for the 10 full-car simulations and five infill points and their rear-wing-only simulation counterparts (it is the full-car values we are minimizing).
