The effect of impeller type on hydrodynamics and concentration distribution of composite wood pellets suspended in water in a stirred reactor

[摘要] Nowadays, it is believed that using biomass has more advantages and benefits than using fossil fuels and oils. So, it should be kept in mind that studies around this subject could have impressive effects on the life of humans and even the planet in the future. This thesis describes the effect of impeller types on hydrodynamics and concentration distribution of composite wood pellets suspended in water in a stirred reactor. These effects are studied by conducting several experiments in order to examine three types of impellers; six-bladed Rushton turbine impeller, six-bladed pitched blade impeller and helical screw impeller. Then by measuring torque and impeller speeds, which were followed by estimation of power consumption and energy dissipation rates, the results were analysed and evaluated to figure out the most suitable and beneficial type of impeller, which can be used in industries. At the end of this research, it was found that the most suitable impeller for this study would be evaluated by parameters such as: power consumption, energy dissipation rates, minimum impeller speed and viscosity.
