Agitation Torque and Energy Efficiency on Liquid-Liquid Dispersion

抄録

In this paper, it is purpose to measure the agitation torque for the breakup of droplet and to require the energy efficiency of agitation in the wide range of particle size from 1μ to 100μ. The values of torque are measured by rotary torque meter adapted to the middle of rotary shaft of agitator. The photographs of drop are taken by a microscopic method. Then, each mean surface volume diameter is calculated and still more energy efficiency of agitation is required. So, the following results are obtained. 1) Agitation torque is proportional to 2.038 power of revolution number. 2) Agitation torque is proportional to 5.188 power of impeller diameter. 3) A relationship of specific interfacial area to agitation torque is shown as next experimental equation.log S=0.3994 log P+0.37575
