摘要:
根据气固两相流理论,通过分析生物质秸秆干燥过程的特点,建立了生物质秸秆在水平直管气流干燥过程中传热传质数学模型,并采用数值方法对模型进行了求解,对干燥过程中物料和空气的含湿量、温度及速度的变化进行模拟仿真.同时分别就气固比和气流初始温度对干燥效果的影响进行模拟,并分析了现象产生的原因.
Abstract:
Through the analysis of the characteristics of the drying process of biomass stalk,a numerical model to describe the heat and mass transfer process in pneumatic drying of biomass stalk in straight level has been presented,based on two-phase flow theory.The model has been used to simulate the change of moisture content,temperature and change of speed of the materials and air in the drying process.The influences of gas-solid mass ratio and initial temperature to the drying process were simulated.The cause of ...
