Research Outline

Our modeling and experimental methodology aim to contribute to the advancement of general knowledge in engine tribology & engine/battery cooling systems. An in-house built tribological experimental apparatus along with Computational Fluid Dynamics simulation results are being used for the development of next-generation ICEs (NG-ICEs), which are fueled by ammonia. From the tribological perspective, engine Piston - cylinder Liner Interaction (PLI) accounts for roughly 10% of total mechanical losses in a conventional ICE. By decreasing these losses, created during the reciprocating motion of the piston, NG-ICEs can benefit greatly to further improving their efficiencies, enabling "greener" transportation.
We are also focusing on the effect of surface characteristics on heat transfer enhancement due to nucleate boiling phenomenon by altering bubble generation frequency from a heated surface. Electrical Discharge Machining (EDM) method is being adapted to create functional surfaces that can enhance heat transfer mechanism. The know-how will be used to minimize the size and the weight of the conventional cooling systems for next-generation engines/batteries. 
In addition, utilization of deep learning models is being to further improve our understanding on these topics and further improve the adaptability of these technologies.
