This paper presents numerical simulations of streamlined adaptive wall control for a two dimensional wind tunnel. Numerical inner and outer flows of the wind tunnel are calculated simultaneously and independently on the basis of Euler equations using a finite difference method in the Cartesian grid. The concept of the adaptive wall requires that the inner flow match the outer flow at control surfaces. This requirement is satisfied by matching the pressure at two independent wall surfaces. Numerical wind tunnel tests of NACA0012 and CAST10 airfoils were performed to demonstrate the potential applications of the adaptive wall control. Several calculated results of airfoil abilities in the numerical wind tunnel are compared with experimental and with other calculated results.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
