Yunyong P. Utiskul, Ph.D., CFEI

Dr. Utiskul applies his knowledge of fire protection engineering, heat transfer, and fluid dynamics principles to the analysis of building fire and life safety systems, occupant egress analysis, smoke management designs, compartment fire modeling (zone and field model), performance-based design, and structural fire protection analysis. He has experience in applications of the various model codes, such as the International Building Code (IBC), and inspection and testing of fire protection systems, including automatic fire suppression systems and automatic fire alarm and detection systems in high-risk occupancies.

Dr. Utiskul’s research focused on fully-developed compartment fires. His research was aimed at development of a model that can predict the compartment fire fuel mass loss rate, gas temperature, and specie mass fraction for any fuel, scale, and ventilation. The developed one-zone model has incorporated the fuel response to flame and its surroundings, which are essential to predict the true fuel mass loss rate in compartment fires. Dr. Utiskul performed small and mid-scale compartment fire tests to characterize the burning behavior in various ventilation conditions. Through his study, justification for a one-zone model and a near-vent mixing algorithm has been established. Dr. Utiskul also has expertise with scale modeling and generalizations of the experimental data to show the dependency of interested variables on governing factors.

Prior to joining Exponent, Dr. Utiskul served as a Fire Engineer for a large international engineering firm, where he provided building code and fire engineering consulting services for domestic and international projects, including: a high-rise casino resort with the area of more than 10 million sq ft in Macau SAR, a multi-use development building in Abu Dhabi, a 33-story high-rise residential condominium in Los Angeles, and an 8-story office building in West Hollywood. He has been involved in the fire and life safety design of buildings with a wide range of occupancy type and project size, from a small office building to a large multi-use hotel casino resort.
