Phillip Johnson

Phillip holds a bachelor’s degree from Union University with a double major in Mechanical Engineering and Mathematics. He entered the EECE program at Washington University in St. Louis in 2014, joining the Kumfer group in 2016, where he studies semi-empirical soot formation modeling. He is co-advised by Prof. Rajan Chakrabarty

The presence of soot in industrial applications plays an important role for radiation heat transfer and emissions. Therefore, soot volume fraction is often calculated in combustion models for such applications, where the complexity of modeling has led to retained use of semi-empirical models. However, many of these models were developed under flame conditions that raise questions concerning their use for coal combustion. Further, soot modeling is important for developing technologies such as oxy-combustion, where flame conditions are outside those traditionally encountered in studies that generated such models. Phillip’s research 1) investigates pre-existing semi-empirical soot models and their performance under a wide variety of flame conditions and 2) aims to develop new soot models where pre-existing ones fail to meet standards of accuracy and to validate them against experimental soot measurements for such conditions.
