Job Summary

GAF R&D is looking for a computational scientist to develop and apply simulation methods for asphalt modification, transport and coating processes, including lab-scale and production-scale CFD (computational fluid dynamics) models. The ideal candidate will have experience with modeling newtonian and non-newtonian complex fluids as well as developing reduced-order models and digital twins based on those simulations. Activities will focus on the improvement and development of simulation methods, the experimental validation of those models and the optimization of equipment and processes to improve our roofing asphalt operations.

Essential Duties

Specific responsibilities include, but are not limited to:

Identifying problems that are uniquely suitable to be solved using a computational fluid dynamics (CFD) approach

Setting up, performing and analyzing computational fluid dynamics models for complex fluids and multi-component flow

Developing reduced-order models based on results from computational fluid dynamics simulations

Actively participating in project teams within R&D and operations

Writing project reports and presenting simulation results in internal meetings

Making simulation results available and usable by non-CFD experts

Qualifications Required

MS Degree with a minimum of 2 years relevant experience OR PhD degree in a relevant field (e.g. chemical engineering, mechanical engineering, mathematics, physics, etc…)

Solid background in numerical methods and computational fluid dynamics of complex and/or multicomponent fluids

Experience using commercial or open-source CFD software (such as OpenFOAM, Ansys Fluent, etc,) as well as basic knowledge in programing languages (Phyton, C++)

Experience with the development and and experimental validation of simulation methods in an industrial setting

Experience working as part of a team and collaborating with experimental scientists to solve problems

Experience running simulations in Linux-based HPC clusters.

Travel Requirements: up to 10%
