The basic design principles for a magnetic suspension and balance system applied to the test section of an ultra-high Reynolds number facility are defined. The design of the cross-sectional area to be used in the test section is analyzed. The parameters of the permanent magnet to be used in the model inside the test section are investigated. The testing of magnetic fields at the center of a test pipe and validation of data by computer finite element analysis is described with the purpose of finding common results. The performance of the magnet configuration is evaluated with relation to the magnetic fields needed at the center of the test section. Once different cross-sectional design envelopes were analyzed for the largest possible cross-sectional area, a modified octagonal cross-section was found to meet the requirements. By the use of AutoCADTM, the parameters to be used for the permanent magnet inside the model were determined. The experimental data obtained for the magnetic fields at the center of a test pipe was validated by the computational data by showing these results to be similar. It was also observed that the magnet configuration most likely to provide the magnetic fields needed at the center of the test section would be: Two large coils around the test section, two coils on top and two coils underneath, and two coils to each side of the test section.
