CFD simulations of ships in high waves

With a growing competition in the marine industry, it is of great importance to have efficient methods of assessing new products. Hull design has traditionally relied on extensive model testing, but recent decades have shown that computational fluid dynamics (CFD) is a useful tool to reduce project costs and lead times. Since CFD simulations of a new hull geometry can be set up and run in a few days, they can play an important role in finding the right balance between parameters such as calm water resistance, propeller-hull interaction and seakeeping ability.

Effects of meshing strategies on in-cylinder flows

The presentation shows the impact of different meshing strategies on the simulation of the in-cylinder flow structure of the Transparent Combustion Chamber (TCC) engine. Large Eddy Simulation of several consecutive engine cycles are compared to experimental measurements, and the impact of the adopted meshing trategy on both accuracy and computational efficiency is evaluated.

Piston bowl optimization using STAR-CD and HEEDS

A multi-objective optimization is carried out to drive bowl shape and injector optimization of a CI engine for automotive application.

Both full-load and part-load operations are simulatenously accounted for in the optimization loop in order to cover a reasonably broad range of engine operations.
