... full-scale experiments on towing non-tabular icebergs of various sizes were conducted in open water conditions. After further processing, 39 pairs of values "Towing force - Iceberg speed" in stationary towing regime were analyzed, with known geometric parameters of the iceberg above-water part. Based...

To study the relationship between local centre-to-centre separation and shedding regimes in tandem arrangements, extensive experiments (Zdravkovich, 1977; Igarashi, 1981) and computations (Meneghini, 2001) had been conducted. Those studies indicated that the occurrence of the bi-stable depended on L/D...
