dc.description.abstractA new mixer had been developed for biofuel using the effect of different geometrical configurations. Standard k-e model in conjunction with sliding mesh method was employed. The flow pattern and distribution of energy dissipation rate in the different geometries have been numerically investigated. In this work a new mixer configuration has been proposed for better mixing.This mixer is a type of rotor stator mixer which has 6 rows of 210 stator holes with equal distribution in alternate pattern. These holes have 22.5° inclinations towards the rotational axis. The proposed mixer design is analyzed qualitatively and quantitative manner and compared with the existing mixers. The flow pattern, mixing parameters and distribution of energy dissipation rate in proposed mixer have been numerically investigated. For the investigation of the mixing parameter water is employed as mixing fluid. Jet emerging from the stator hole in the tank is examined using different velocity profiles at different position. Furthermore, energy dissipation rate in the tank also implied for confirming the superiority of the proposed mixer in the biofuel. The proposed mixer design has approximately 2 times more efficiency as compare to the existing rotor stator mixer on the basis of mass flow rate in the rotor region. It is also observed that 70% energy is dissipated in the rotor region at 4000 rpm. Because of the higher pressure gradient in the rotor swept region, greater flow rate is reported in the proposed rotor stator mixer as compared to the existing mixers. Therefore better mixing is obtained. The power number correlated well with the total flow rate and the total flow rate correlated well with the total hole area. Jets emerging from the stator spreads in the widen area which produce greater range of radial and tangential velocity agreement. High energy dissipation rate occurred in the regions around the leading and trailing edges due to stagnations in those regions. Stators with inclined holes generated more uniform energy dissipation rate profile around the holes than those with wide holes since the regions with high energy dissipation rate around the leading and trailing edges get merged.en_US
