Sebastian Chialvo, Ph.D.

Senior Consultant

Dr. Sebastian Chialvo has a Ph.D. in chemical engineering and specializes in modeling fluid flow, heat transfer, and reacting systems.  He is an expert in computational fluid dynamics (CFD) and, more specifically, in developing and utilizing CFD models to solve complex flow problems rapidly and accurately.  He has used these approaches to understand and quantify loss of containment, atmospheric dispersion, wind loads, fluid mixing, erosion and corrosion, noise and vibration, thermal fatigue, equipment fouling, reactor runaway, and reactor product quality issues.

Prior to joining ESi, Dr. Chialvo worked for eight years at ExxonMobil Research and Engineering where he supported numerous projects for oil production, refining, and chemicals production.  He also served as group lead for its fluid dynamics group and held technical quality oversight responsibilities for others’ work in fluid dynamics and CFD modeling. His experience includes investigating root causes of safety and environmental incidents (as well as preventing them before they happen), identifying chemical process and equipment improvements to enhance throughput and reliability, and research into novel chemical and petrochemical process technologies.  His work spanned a diverse range of application areas including catalytic and thermal cracking, polymerization, catalyst manufacturing, drying, multiphase separations, spray systems, heat exchangers, flares, and pipelines.
