The ERCOFTAC (European Research Community on Flow, Turbulence and Combustion) Seminar and Workshop was held with the aim of sharing between academic and industrial organisations information on the state of the art of 3D flow calculations for turbomachines. An important objective was the educational element for both established workers and new researches in the area. The philosophy was one of openness and sharing of both successes and problems. Four test cases were selected from the open literature covering a range of turbomachinery configurations. Five review lectures were given to provide a background for the discussion of the computational results. The workshop sessions indicated the importance of ensuring numerical accuracy, the need for future work particularly in turbulence and transition modelling, and the possibilities of adaptive and unstructured grids. Industrial participation was rather low and the problems in allocating resources by an organisation for this sort of exercise are recognised, and should be carefully considered for any future similar event.
