SIG10

Transition Modelling

Purpose and focus of SIG

The aim of the ERCOFTAC SIG10 on “transition modelling” is development and testing of models for transition of laminar to turbulent state of boundary layer flows. Flow configurations may be internal (turbomachinery) or external (aircraft). The activities include experimental analysis and fundamental simulations (DNS, LES) with the aim of understanding transition mechanisms and determining characteristic parameters useful for modelling. Current transition models are meant for combination with turbulence models for RANS description of flows, but a further step may be models for combination with hybrid RANS/LES flow description. 


SIG10 and ETMM12

SIG10 is the organiser of a mini-symposium on transition modelling with two sessions of each 5 papers at the 12th International ERCOFTAC Symposium on Engineering Turbulence Modelling and Measurements (ETMM12) in Montpellier, September 26-28, 2018.

The program of ETMM12 is available on: http://etmm.science/
