Doctoral Dissertation Topic: Comparison Of Radial Flow And Down Flow Reactor For Hydroprocessing: Experiments And CFD Simulations
    Three phase radial flow reactor configuration having complex multiphase interactions of gas, liquid and solid catalyst have not been explored so far. Understanding of key hydrodynamic parameters like operating range, pressure drop and liquid holdup is critical for design and performance evaluation of this novel configuration. In order to assess effectiveness of unexplored radial flow configuration vis-à-vis conventional trickle flow, understanding of hydrodynamics is a critical task. Present research is focused on characterization of the hydrodynamics of radial-flow reactor vis-à-vis trickle bed reactor.
