New Pub­li­ca­tion on Sim­u­la­tion-Driven Design of a Fast Monohull

Check out our latest pub­li­ca­tion on ​‘Sim­u­la­tion-driven design of a fast monohull’ that is publicly avail­able for you to read.

A fast monohull was designed and opti­mized, using CAESES for para­met­ric modeling and opti­miza­tion coupled to STAR-CCM + for free-surface RANS sim­u­la­tions. The boat is a 9.5ton pilot boat, fea­tur­ing tunneled pro­pellers, shafts, and rudders. The geometry of the bare hull and tunnel were varied during the opti­miza­tions, using fully-para­met­ric CAESES models.

The opti­miza­tions of the bare hull with tunnels were under­taken for thrust at the design speed of 27.5kn. The boat was free to trim and rise, uti­liz­ing an overset grid for high res­o­lu­tion and accept­able turn-around time.

A sys­tem­atic com­par­i­son of numer­i­cal and exper­i­men­tal data was under­taken. The exper­i­ments were con­ducted with the high-speed carriage at TU Berlin, using a 3.5m fully-appended self-pro­pelled model. The opti­miza­tions com­prised Design-of-Exper­i­ments, deter­min­is­tic searches, sur­ro­gates, and global strate­gies. Sub­stan­tial improve­ments were found with variants being more energy-effi­cient than a rep­re­sen­ta­tive baseline. The paper dis­cusses modeling, sim­u­la­tions, and opti­miza­tions along with selected results.
