Mohammad Karimi Zand gave a presentation entitled “A new lift model for the Euler-Lagrange LES of bubble plumes” at the ERCOFTAC Workshop held in Delft, Netherlands, from 20 to 22 May 2026.

The goal of the bi-annual DLES workshop series is to establish the state of the art in Direct Numerical Simulation, Large Eddy Simulation, and related hybrid techniques that resolve instantaneous flow structures either partially or fully.

Mohammad’s talk presented the latest result of his PhD project, which is a newly proposed lift force model for bubbly plume simulations. This novel lift model, which incorporates physical properties inherent to the plume flow, shows great signs of generality for using in different industrial applications. The physical quantities which directly influence the bubble lateral movements are not only the bubble size and void fraction, but also turbulence decay rate and vorticity, which should be considered for improving the model even further for highly dynamic flow conditions such as plumes rising in a cross-flow.
