Force and Heat Transfer on a Delta Wing in Rarefied Flow

For testing numerical methods in the rearefied regime a broad range in parameter variation, especially in the Knudsen number is advisable. Therefore the drag, lift total heat transfer and recovery temperatureof a small delta wing (5mm length) was tested in a sonic orifice free jet flow. In this report the experimental technique and the main results will be given. Details are given in Ref.1 where also different correlation parameters are examined by comparing experimental and theoretical results, especially of the workshops in Antibes 1990 and 1991.
