MHD supersonic flow control: OpenFOAM simulation [PDF]
Proceedings of the Institute for System Programming of the RAS, 2016 MHD flow control is a relevant topic in today’s aerospace engineering. An OpenFOAM density-based solver that is capable of handling MHD supersonic flow problems with constant magnetic field is developed. The proposed solver is based on Balbas-Tadmor central difference schemes.

International Journal for Numerical Methods in Fluids, EarlyView.This study presents an efficient method to compute polymer stress‐tensor components in viscoelastic laminar jet flows using models such as Oldroyd‐B, Giesekus, PTT, and FENE. By assuming a stationary and parallel flow, the methodology significantly reduces computational cost.

Experimental Study on Polymer–Polymer Interfacial Thermal Resistance
Macromolecular Theory and Simulations, Volume 34, Issue 2, March 2025.Interfacial thermal resistance (ITR) in polymer–polymer interfaces is experimentally measured in this paper by the multi‐layered bulk sample approach. Based on numerical simulation and experimental verification, new techniques of layer‐overlapping samples are developed.

gdbOF: A debugging tool for OpenFOAM® [PDF]
Advances in Engineering Software, 2012 OpenFOAM(R) libraries are a great contribution to CFD community and a powerful way to create solvers and other tools. Nevertheless in this creative process a deep knowledge is needed concerning with classes structure, for value storage in geometric fields and also for matrices resulting from equation systems, becoming a hard task for debugging. To help

International Journal for Numerical Methods in Fluids, Volume 98, Issue 3, Page 321-347, March 2026.A hybrid RANS‐LES turbulence model adapted for the Moving Particle Semi‐implicit method is employed to investigate a turbulent free surface flow. A method based on the cell‐linked list is proposed to speed up the nearest wall search for the turbulence model.
