DNV GL’s new “Virtual Trial” application allows yards and owners to use computational fluid dynamics (CFD) simulation to analyze, compare and benchmark the fuel efficiency of hull design variants at full-scale. The results are available within one week, in a web-based report where users can see the CFD results and hull lines in 3D and gain more insight into flow details, the company said in its press release.
As CFD simulation technology has matured it has become a viable alternative to traditional model basin tests, while reducing lead time and costs. However, the computer resources and expert know how to design and carry out such tests are still not wide spread.
The Virtual Trial application, removes the need for expert support by streamlining and automating the CFD simulation process. Without the need for any CFD specific input, users can conduct fully automated full-scale RANSE (Reynolds-averaged Navier-Stokes equations) VoF (Volume of Fluid) CFD simulations on the resistance and propulsion of their vessel. Users can upload individual vessel hull forms, run simulations with pre-set parameters and then easily compare their results against the results of similar vessels in the Virtual Trial database. Whether for a newbuilding or retrofit project, Virtual Trial reduces the barriers to full-scale CFD simulation testing and comparative benchmarking.
