The process or state in which solid particles or powders are agitated by a gas or liquid flow so that they behave like a fluid; used in chemical and materials engineering.
流動化装置で砂粒を空気で流動化させて、反応効率を調べた。
We fluidized sand particles with air in a fluidization apparatus to study reaction efficiency.
流動化床反応器は触媒と粒子の接触を良くするために、粉体の流動化を利用する。
Fluidized-bed reactors use fluidization of powders to improve contact between the catalyst and particles.
粉体の流動化条件（気流速度や粒径）を最適化する必要がある。
It is necessary to optimize powder fluidization conditions (airflow velocity, particle size).
