| The infuences of sound pressure, sound wave frequency, bed temperature and size of the particals on the heat transfer in a bubbling fluidized bed reactor with diameter of 50 mm and hight of 1000mm, filled wiht the average diameter dp of 1200 um glass beads and 398um quarts sands and SiO2, were exmamined. The results showed that the heat transfer property of the high-temperature bed reactor can be greatly enhanced with the introduction of sound field. The heat transfer coefficient increase with the increasing sound pressure grade and the bed temperatue and decreases with the smaller partical size...... |
