DNS and unsteady RANS for rotating machinery
Abstract
In this project we will do computational
fluid dynamics simulations (CFD), using the Fluent and
Star-CCM+ CFD tools. We will use the clusters for mainly
two differet projects:
1-BYEFOULING project:
Chalmers is a part of a big EU project (EU FP7). The main
goal of BYEFOULING is to design, develop and upscale
antifouling coatings with enhanced performance compared
to current available products. The approach in
BYEFOULING is to tackle the different stages of the
biofouling process using innovative antifouling agents,
covering surface-structured materials, protein adsorption
inhibitors, quorum sensing inhibitors, natural biocides and
microorganisms with antifouling properties. Chalmers
responsibility as the WP6's leader is to predict drag
reduction for BYEFOULING coatings. The drag reduction
analysis will be performed by direct numerical simulations
(DNS) and large eddy simulations (LES) of fluid flow on ship hulls.
2-Aero engine efficiency improvement:
Commercial air transport is growing rapidly and is expected to increase by around 4.5% in terms of passenger kilometres over the next 20 years. To green aviation access to large volumes of liquid fuels with no or limited CO2 impact (bio-fuels) are needed. To limit the need for the earth’s resources, radical efficiency improvement is needed provided by the innovative heat exchanger concepts that will be demonstrated through this project.
In this project novel aerodynamic and heat transfer designs will be studied with ANSYS CFD and optimization tools.
