Two rakes of cross-wire probes were used to capture the two-point velocity statistics in a flow through an axisymmetric sudden expansion. The expansion ratio of the facility is 3, and has a constant geometry. Measurements were acquired at a Reynolds number equal to 54,000 based on centerline velocity and inlet pipe diameter. The two-point velocity correlations were obtained along a plane normal to the flow (r, θ), at eleven downstream step-height positions spanning from the recirculating region, through reattachment, and into the redeveloping region of the flow. Measurements were acquired by means of a flying hot-wire technique to overcome rectification errors near the outer wall of the pipe where flow recirculations were greatest. A mixed application of Proper Orthogonal (in radius) and Fourier Decomposition (in azimuth) was performed at each streamwise location to
ATHABASCA UNIVERSITY is an open, distance university located in Athabasca, Alberta. Its mandate is to break down barriers that traditionally restrict access to university-level education. This mandate is interpreted broadly to include constraints of time, space, educational background, and social position. In the latter case, the university offers innovative programmes in the areas of women's studies, native studies, and labour studies. Athabasca University's Labour Studies programme is one of a small number of similar programmes in Canada. It is unique in a couple of ways. For one dung, like all of Athabasca's programmes it is available entirely through distance education, making it the only distance education labour studies programme in the world to our knowledge. It is also unique in that the programme has a mandate to provide education to its adult constituency, which in the first instance is the Albeitan and Canadian labour movements. One of the ways this mandate is achieved is to collaborate with organizations, services, and educators in the labour movement. In one such collaboration Athabasca University is cooperating with die Canadian Union of Public Employees (CUPE) and the Solidarity Network (SoliNet). CUPE is Canada's largest union, with over 400,000 members in 2200 locals scattered across die country. It represents public sector workers in hospitals, schools, municipalities, and other such workplaces. SoliNet is an electronic mail and computer conferencing system owned and operated by CUPE since 1987, and made available to die Canadian labour movement generally. It links over 1000 users from across die country, as well as some subscribers from the USA and other countries, providing a vital information medium that is unconstrained by time and physical space. It is apparent both to CUPE and to Athabasca University that collaboration is mutually beneficial. It is in CUPE's interest to expand its educational offerings on SoliNet. Indeed, one of SoliNet's educational ideals always has been to offer an on-line university labour programme. Similarly,
