Density-based topology optimization for turbulent fluid flow using the standard k-epsilon RANS model with wall-functions imposed through an implicit wall penalty formulation
Amirhossein Bayat, Hao Li, Joe Alexandersen
Turbulent flows have high requirements for very fine meshes near the boundary to ensure accuracy. In the context of topology optimization (TO), such fine meshes become unrealistic…
Revisiting the origin to bridge a gap between topology and topography optimisation of fluid flow problems
Joe Alexandersen
This paper revisits the origin of topology optimisation for fluid flow problems, namely the Poiseuille-based frictional resistance term used to parametrise regions of solid and flu…
Topology Optimization of Two Fluid Heat Exchangers
Lukas Christan Høghøj, Daniel Ruberg Nørhave, Joe Alexandersen +2
A method for density-based topology optimization of heat exchangers with two fluids is proposed. The goal of the optimization process is to maximize the heat transfer from one flui…
Topology optimization of heat sinks for instantaneous chip cooling using a transient pseudo-3D thermofluid model
Tao Zeng, Hu Wang, Mengzhu Yang +1
With the increasing power density of electronics components, the heat dissipation capacity of heat sinks gradually becomes a bottleneck. Many structural optimization methods, inclu…
Large scale three-dimensional topology optimisation of heat sinks cooled by natural convection
Joe Alexandersen, Ole Sigmund, Niels Aage
This work presents the application of density-based topology optimisation to the design of three-dimensional heat sinks cooled by natural convection. The governing equations are th…
Topology optimisation for natural convection problems
Joe Alexandersen, Niels Aage, Casper Schousboe Andreasen +1
This paper demonstrates the application of the density-based topology optimisation approach for the design of heat sinks and micropumps based on natural convection effects. The pro…
