IS11 - High-fidelity Simulations in Marine Engineering Problems
The growing computing power of supercomputers during the last few years allowed
scientists to exploit the predictive capabilities of eddy-resolving methodologies in
marine engineering, including, for example, naval hydrodynamics and marine energy
problems [1,2]. In particular, parallel computing and GPU accelerators enabled the
simulation of practical flow problems on grids consisting of hundreds of millions or
billions of points to resolve the Navier-Stokes equations by means of Large-Eddy
Simulation (LES), Detached-Eddy Simulation (DES) or wall-modeled LES. Many times
these methodologies are adopted in the framework of multi-fidelity approaches, where,
for instance, eddy-resolving techniques are coupled with models mimicking the action
of the bodies immersed within the flow using actuator disks or actuator lines models.
The latter are utilized, for instance, to simulate propellers working on ships and
submarines as well as turbines in hydrokinetic farms, where the flow problem involves
a wide range of scales. Although the solution of marine engineering problems in full
scale by geometry-resolving LES or DES is still very challenging, the information
provided by high-fidelity techniques at model scale is a critical reference for tuning
lower-fidelity approaches and, more in general, to develop an improved insight on the
complex flow phenomena.
In this session we invite the submission of works dealing with relevant marine
engineering problems (such as marine propulsion and hydrokinetic energy, among
others) where the predictive capabilities of eddy-resolving techniques are utilized in the
framework of high-performance computing to demonstrate the state-of-the-art of
computational fluid dynamics in this field.
