Hydrogen gas is a clean burning fuel suitable for powering public vehicles. Hydrogen fuel has the highest energy density (143 MJ Kg-1 ). This research paper emphasizes on three dimensional hydrodynamics and temperature distribution during photo biohydrogen generation by Rhodobacter sphaeroides strain O.U.001 in a triple jacketed 1 L photobioreactor (PBR). The fermentation broth has turbulent flow conditions and light gradients among various layers, which affect the light conversion efficiency of the PBR. From the carbon source (malic acid), various organic acids are produced within fermentation (lactate, acetate, and formate). Modelling and simulation study by CFD, confirmed uniform fluid dynamics and heat transfer throughout the annular PBR. Modified Gompertz equation gave good simulated fitting with experimental value for H2 generation. Rhodobacter sphaeroides O.U. 001 gave good simulated results for H2 generation by mathematical modelling of substrate consumption kinetics and substrate utilization for biomass.
