This thesis concerns incompressible, planar, two-dimensional flow past impervious and porous bluff membranes as well as impervious streamlined membranes or planar sails. Each membrane was held by two supports which were thin relative to the distance between them. The angle between the flow direction and the line joining the supports was set at right angles for the bluff membranes and at small angles for the streamlined membranes. Experiments were made for various membrane lengths as a proportion of the distance between the supports. Materials of different density and porosity were used for the bluff membranes. A theory, based on Bearman-Fackrell's numerical solution of Parkinson-Jandali's wake-source model for bluff bodies, was developed for the impervious and porous bluff membranes and found to give good prediction of the drag coefficient. Previous theoretical solutions for the planar sail showed serious disagreement with the experimental results mainly because of flow separation.
