要約

Gas-solid flow with bidispersed particles was studied. The distribution has been obtained for the first time of the mean (time-averaged) and fluctuation velocities of bidispersed mixture moving in a turbulent flow of air in a pipe. The measurements results have demonstrated that it is possible in principle to use laser Doppler anemometers (LDA) to study velocity fields for large bidispersed particles having identical optical properties.
