Coupled Hybrid RANS-LES Research at The University of Manchester
Résumé
This short communication summarises recent developments and ongoing work on Hybrid RANS-LES Methods (HRLM) at The University of Manchester. Our work is focussed primarily on the development of coupled zonal methods, investigating improvements and novel applications of embedded turbulence simulation via the Synthetic Eddy Method. These activities are centred around the premise that no single modelling methodology will be generally applicable. Not only does this apply to different test cases, but for particular regions of the flow within a single test case. Similarly, when factoring in the computational resources available to the modern-day CFD practitioner, a framework for multifidelity approaches seems pragmatic. The work presented herein is intended primarily as a window through which we outline our current activities, mostly driven by PhD projects, many of which with industrial projects in mind. We also introduce recent developments focused on using the lattice Boltzmann method as part of a coupled Hybrid RANS LES approach.
