Executive Summary : | Scaled wind tunnel models are used for wind tunnel testing due to tunnel size. Higher size models are always preferable due to model fidelity and obtaining higher Reynolds number. Due to larger model size, wind tunnel models offer blockage to the flow and hence, data obtained is corrupted. This project aims to formulate a computer program to correct the wind tunnel data on general models (slender, wing body and bluff bodies etc.,) by measuring wall pressures and carrying out appropriate corrections on the aerodynamic coefficients. |
