The Artificial Neural Network (ANN) method is applied to intelligent aerodynamic design for airfoils. A Self-Organizing Map (SOM) network is demonstrated selecting referenced airfoils which mostly meet or close to the design requirement from airfoil database. Then a Back-Propagation (BP) network automatically learns the relationship between referenced(More)
Chimera grids method has broad applications in complex flow field simulations because of its convenience of the arbitrary boundary interfaces and the easiness of gird generations of subzones. However, the main disadvantage or challenging difficulty lies in the global conservative information exchange between different zones or components. This work aims at(More)
The vacuum-accumulated energy (VAE) method is presented for simulation of the fluctuation and characteristics of vacuum-energized pressure in a fluidic-conveying line. Based on the energy consumption of the fluidic conveyance, non-continuity, periodicity, the fluidic conveyance Switch-On (FCSO) process, vacuumed-energy consumption process, and vacuum(More)
