An investigation into the characteristics of the flow inside a leading-edge vortex is described. The objective of the investigation is to support the development of mathematical models for leading-edge vortex flow by measuring in detail the flow properties of the conical part of a leading-edge vortex, and by comparing these results with theory. The velocity distribution inside the core is well predicted by Stewardson and Hall's outer solution, and the resulting distributions of the entrainment and circulation correlate well with the measured distributions. The effect of the inclusion of the entrainment on the computed characteristics of a slender delta wing is demonstrated using a higher-order panel method.
