摘要

The two transatlantic liners “Bremen” and “Europa” built by different German ship yards in the 1920ies were reanalysed at HSVA using latest CFD tools. Rediscovering the old lines plans in the archives of Deutsches Schiffahrts Museum in Bremerhaven and at shipyard Blohm & Voss in Hamburg provided the basis for a challenging new project to prove the capabilities of the in-house RANS code FreSCo+ used to compare the performance of the two record holders in calm water and selected sea conditions. Bringing together the lines of the two “look alike” sister ships revealed for the first time the striking overall differences of the design concepts followed by the two builders at the time. Built to the same overall specifications and dimensions, it was obvious from old photographs that the bow sections and specifically the bulb varied in character .Comparing the full lines plans also indicates a significant difference in overall shape. In a first step, the present paper analyses calm water performance of both ships using different CFD prediction methods, potential flow as well as full RANS.rnAs past reports also indicated rather different seakeeping behaviour of both vessels, RANS based motion predictions were performed for a set of significant North Atlantic waves too. These show differences in ship motions and added resistance.rnThe CFD predictions performed shed further light onto the differences of the pioneering hull designs of the tworntransatlantic liners.
