Research Interests

  • Simulation and optimization of energy systems;
  • Model predictive control for nonlinear processes;

Research highlights

Ø  Dynamic modeling and simulation of fixed-bed biomass gasification.

The model is a novel shrinking core kinetic model addressing the peripheral fragmentation pheonmenon

The syngas generation, biochar productions, and PM emission transients can be quantified in a single model

Ø  Numerical data driven model development

The data driven PM emission model developed for gasification solid conversion, which is a radial basis function-based response surface model and employ experimental data pretreated by discrete wavelet transforms.

The artificial neural network model developed for biomass pyrolysis process
