Stefan Belfroid holds a senior scientist position at the TNO department of Heat Transfer and Fluid Dynamics. He holds a MSc in Applied physics (1995) and a MSc in Computational Mechanics (1997). After working for 4 years at Stork he now works for 19 years at TNO. He is active in the fields of dynamic multiphase flow (specializing in slugging and liquid loading in wells) and in flow induced pulsations and vibrations (specifically on the topics of shear layer instabilities at bluff bodies, sidebranches and on riser induced pulsations. The last years he is activity involved in the study of multiphase flow induced forces. The work is mainly done for the Oil & Gas industry and for CCUS projects.

Lyes has been developing in-house codes for numerical simulations of multiphase flows by using the front-tracking and domain decomposition methods. The solver can run on a variety of computer architectures ranging from laptops to supercomputers, including the modules for the flow interactions with the immersed solid objects, contact line dynamics, species and thermal transport with phase changes. Some relevant disciplines include the falling liquid film, droplet impact, direct numerical simulation, multiphase flow, parallel or distributed processing, interface dynamics and front tracking, atomization, and microfluidics.
