RANS, LES or DES? Choosing a turbulence model that fits the question
How RANS, LES and hybrid methods differ in what they resolve, what they cost and which engineering questions each can answer reliably.
INSIGHTS
Notes from the solver.
Practical guidance on turbulence modelling, meshing, verification, heat transfer, quantum chemistry and high-performance computing.
Meshing ·
y⁺ explained: getting the near-wall mesh right
What y⁺ means, why the buffer layer is the awkward zone, and how to estimate the first-cell height before you build the mesh.
Verification ·
Mesh independence and the Grid Convergence Index: how far to trust a CFD number
How a three-mesh study, Richardson extrapolation and the Grid Convergence Index turn mesh independence into a stated numerical uncertainty.
Thermal ·
Conjugate heat transfer for electronics cooling: a practical guide
What conjugate heat transfer couples, where prescribed heat-transfer coefficients fall short, and what an electronics-cooling study should report.
Quantum chemistry ·
DFT in practice: choosing a functional and basis set
A practical route through Jacob's ladder, dispersion corrections and basis-set families to DFT settings you can justify.
HPC ·
Cloud HPC for CFD: how many cores does your simulation really need?
How scaling limits, memory bandwidth and interconnects set the useful core count for a CFD run, and how to plan cloud capacity around them.
