Wall interference studies: Revisited 13; 13;

A brief review is made of the methods currently available for assessing and correcting the data for effects due to wall interference. Computational simulation of ventilated walls has been described. The DLR panel code available in the division is being modified to handle flow past a model with sting and support strut in a wind tunnel whose walls could be either solid, or, ventilated, or, open-jet. The effect of sting, strut, and walls on the model data is under study
