Abstract: This paper gives H-O type grid generation and applies finite-volume method for wing-body flow. A 3-D Euler code for wing-body has been developed. We improve in this code the distribution of the number of the grid points over wing and body surfaces, and keep the trailing edge of the wing being one of the grid lines even when the edge has sweepback or sweep forward. The code developed can provide not only the spanwise pressure distribution as usual on cross-flow planes, but also the chordwise pressure distributions. The computation for NASA TN D-712 wing-body modd with the present code shows that the computed pressure distributions are in very good agreement with the experiment.
