ABSTRACT CTS-9528380 Flow visualization and heat transfer studies of gas-liquid-solid fluidization at pressure up to 22 MPa and temperature up to 200( C will be conducted. The effect of changing the pressure and temperature in three-phase fluidized beds will be investigated. An experimental apparatus has been built to enable PIV visualization and thermal transport experiments. Bubble motion, coalescence and break-up processes will be analyzed based on the measurements. Regime transitions, incipient fluidization, phase holdups and bed expansion/contraction phenomena will be determined for the fluidization system. The local heat transfer characteristics in three-phase flow will be measured using a microfoil heal flow sensor. This project is proposed to be conducted in collaboration with four industrial units (Shell Development Co., Amoco Oil Co., Hydrocarbon Research Inc., and Exxon R&D Co.), under the Grant Opportunities for Academic Liaison with Industry (GOALI) initiative. The project will lead to new knowledge for three-phase flow, with application to design and operation of hydrocarbon processing in fluidized bed reactors of relevance in oil industry. ***

摘要CTS-9528380 将进行压力高达22 MPa、温度高达200 ℃的气-液-固流化的流动显示和传热研究。 将研究改变三相流化床中的压力和温度的影响。 建立了PIV可视化和热输运实验装置。 气泡的运动，合并和破碎过程将根据测量进行分析。 将确定流化系统的状态转换、初始流化、相含率和床层膨胀/收缩现象。 采用微翼式热流传感器测量三相流中的局部换热特性。 该项目拟与四个工业单位（壳牌开发公司，阿莫科石油公司烃研究公司，和Exxon R D Co.），根据赠款机会学术联络与产业（GOALI）倡议。 该项目将导致三相流的新知识，并应用于石油工业相关流化床反应器中烃加工的设计和操作。 ***
