Paul Williamson specializes in fluid dynamics modeling and one- and three-dimensional computational fluid dynamics (CFD) for complex industrial systems. He models water-deluge systems and service reservoirs; analyzes oil and gas fires, including jet, spray, and pool fires; and evaluates gas-turbine enclosure ventilation, hydrogen ventilation, and lithium-ion battery safety. He applies steady-state and transient simulations, pressure-transient analysis, and network modeling to assess system performance, operational risks, and fire-safety conditions. His experience spans energy, industrial, and transportation applications, including hazardous-fluid handling, fuel storage, and decarbonization projects. He also collaborates with Thornton Tomasetti’s global practices to develop practical analytical methods for emerging engineering challenges.
