    Optimization using surrogate models and partially converged computational fluid dynamics simulations

    No full text
    Efficient methods for global aerodynamic optimization using computational fluid dynamics simulations should aim to reduce both the time taken to evaluate design concepts and the number of evaluations needed for optimization. This paper investigates methods for improving such efficiency through the use of partially converged computational fluid dynamics results. These allow surrogate models to be built in a fraction of the time required for models based on converged results. The proposed optimization methodologies increase the speed of convergence to a global optimum while the computer resources expended in areas of poor designs are reduced. A strategy which combines a global approximation built using partially converged simulations with expected improvement updates of converged simulations is shown to outperform a traditional surrogate-based optimization

    Black-box calibration for complex systems simulation

    No full text
    Predicting or measuring the output of complex systems is an important and challenging part of many areas of science. If multiple observations are required for parameter studies and optimization, accurate, computationally intensive predictions or expensive experiments are intractable. This paper looks at the use of Gaussian process based correlations to correct simple computer models with sparse data from physical experiments or more complex computer models. In essence, physics based computer codes and experiments are replaced by fast problem specific statistics based codes. Two aerodynamic design examples are presented. First a cheap two dimensional potential flow solver is calibrated to represent the flow over the wing of an unmanned air vehicle. The rear wing of a racing car is then optimized using rear wing simulations calibrated to include the effects of the flow over the whole car
