Research Interest

My research focuses on unit design, optimization, and scale up using computational fluid dynamic (CFD) modeling. Research interest includes purification and separation processes, renewable energy production and storage, heat transfer and ventilation systems, and dispersed multiphase flows


  • Modeling of turbulent multiphase flow in industrial freezers
  • Design, optimization, and scale up of chromatographic purification process of free lutein
  • Simulation of mixing tank for production of fruit coating mixture (water-wax)
  • Simulation of ZnO nanoparticle synthesis in tubular reactor
  • Simulation of indoor climate inside animal houses
  • Design and optimization of flow-battery systems and biomass gasification process
