Research Themes

   The following research themes are current topics of interest among researchers from industries, Ph.D, MS and BS students at Kusaka Laboratory.
1) Numerical simulation of radical nucleation, surface growth-oxidation, and coagulation processes, combined with detailed chemistry. 2) Experimental investigation of knock occurrence by the use of a single cylinder gasoline engine and its modeling. 3) Diesel Spray Combustion Modeling 
4) Simultaneous improvement of fuel consumption and exhaust gas emissions of passenger car Diesel engines with a 4-way catalyst. CFD codes combined with detailed chemistry or surface chemistry are also used to analyze in-cylinder or in the catalyst phenomena. 5) Experimental studies on urea SCR(Selective Catalytic Reduction) for heavy duty trucks by the use of a mini-reactor. One and two-dimensional models coupled with surface chemistry are also developed to optimize the urea injection patters and porosity, configurational diffusivity in the catalyst layer. 6) Experimental studies on DPF(Diesel Particurate Filter) and SCR coat DPF for heavy duty trucks and passenger vehicles by the use of a mini reactor. A quasi-two dimensional simulation is also conducted to predict pressure drop, velocity distribution and velocity in the wall in a DPF during CR(Continuous Regeneration) and FR(Forced Regeneration) modes. 7) Model based control for passenger car Diesel engines to improve fuel consumption and exhaust gas emissions simultaneously. 8) Transport phenomena occurred in a fuel cell and its modeling. 9)Transport phenomena occurred in a Li-ion battery and its modeling 10) Optimization for componets in HEVs
  Most projects are financially supported by industries, governments in Japan. A total of two Ph.D students, fourteen MS students and seven BS students are currently involved in these research projects.
