Dr. Hur specializes in failure investigation and design/performance/safety reviews of rotating machinery, and thermal-fluid systems and processes. He applies his expertise in fluid dynamics, thermodynamics and rotor-dynamics in the analysis of rotating turbo machinery such as gas turbine engines, compressors, pumps, steam turbines, and motor vehicle components. Dr. Hur uses both experimentation and analytical/computational modeling approaches to solve engineering problems.

Dr. Hur's expertise is used in a variety of litigation and arbitration matters. Dr. Hur has investigated failures of various turbomachinery for a range of applications from small-scale kitchen blenders, to medium-scale steam turbines in process plants, to large-scale industrial gas turbines for power generation. In addition to rotating machinery, Dr. Hur applies his expertise in fluid dynamics and heat transfer across a wide range of complex engineering problems involving fires, explosions, pipe flow-induced vibrations and off-gassing of air pollutants. His project experience also includes battery systems, wearable electronics and household appliances. 

Prior to joining Ä¢¹½tv, Dr. Hur was a PhD candidate in the Gas Turbine Laboratory at the Massachusetts Institute of Technology. At MIT, he developed a novel forced-response system identification methodology for measuring rotordynamic damping in a full gas turbine aero-engine. During this process he developed a reduced-order modeling framework that captures the full engine dynamics to simulate realistic conditions and characterized the approach using statistical analysis. He devised and proposed guidelines for designing and executing forced-response experiments for aero-engine rotors. He also designed and commissioned an experimental facility for testing a commercial turbofan engine. In addition, in the Whittle Lab at the University of Cambridge, he performed compressor stall experiments to characterize the effect of rotor blade mis-staggering on the onset of premature stall. Dr. Hur's experience also includes wind tunnel testing and experimental analysis of heat sinks for turbo-electric aircraft application.

Prior to graduate school, Dr. Hur was a research engineer at STI C&D in South Korea, where he developed optimal flow patterns in molten metal die-casting of various automobile components using computational fluid dynamics (CFD). He also has experience in analyzing and improving molten steel transport and discharge processes.
