The case is a nominally two-dimensional isothermal flow through a staggered tube bundle array.
The experimental test section consists of 7 horizontal, staggered rows of rods, as shown in figure 1, across which water flows at an average velocity of 1.06 m/s. With this value, and a tube diameter of 21.7 mm, the Reynolds number (based on that diameter) is 18000. LDA measurements, taken across the spanwise centre plane, indicate that the flow becomes periodic around the fourth row from the bottom.
On the assumption that the flow is fully periodic and steady, the computational domain may be reduced to the passage shown in figure 2 below, with suitable periodic conditions applied in the spanwise and streamwise directions.
Data is available in the form of profiles of mean velocities \(U\) and \(V\) and Reynolds stresses \(\overline{u^2}\), \(\overline{v^2}\), \(\overline{uv}\), along the lines \(x=0\), \(11\) and \(16.5\) mm and \(y=0\) and \(22.5\) mm.
Measurements of the velocities were obtained using LDA. Most data were obtained in a subdomain surrounding a tube in the fifth row, where the flow appeared to have reached a periodic state.
Profiles of \(U\), \(V\), \(\overline{u^2}\), \(\overline{v^2}\), and \(\overline{uv}\) are available along three horizontal lines (\(x=0\), \(11\) and \(16.5\) mm) and 2 vertical lines (\(y=0\) and \(22.5\) mm).
Sample plots of selected quantities are available.

The flow formed one of the testcases studied in the 2nd ERCOFTAC/IAHR Workshop on Refined Flow Modelling, held at UMIST, Manchester, UK in June 1993.
