查询词典 calculate

The waste combustion in the waste bed and the impacts of the waste burning efficiency are complex. In order to solve this problem, the method of numerical simulation has been adopted to simulate waste combustion, and calculate the mass loss rate, moisture evaporation, volatile release, char burning rate. Used the total flow rate of primary air between 50～1 000 Nm3/min to calculate the mass loss, excess air coefficient of waste bed, components of the gas. Calculated results show that the burning efficiency is higher when the total flow rate of primary air is at 517.47～632.09 Nm3/min .

However, it is not accurate to calculate the problem of continuum media. The FEM may forecast the failure area of the material reasonably, whilst it is hard to calculate the failure process in brittle media.

有限元法适于预测脆性材料损伤和破坏的区域，但难以直接用于计算和模拟脆性材料及结构发生破坏的整个过程。

The discrete element method and the finite element method have their own advantages and weaknesses. Basically, the DEM was developed for predicting the failure problems accompanying with the transition from continuum to non-continuum media. However, it is not accurate to calculate the problem of continuum media. The FEM may forecast the failure area of the material reasonably, while it is hard to calculate the failure process in brittle media. Therefore it becomes a good choice to combine the two methods to construct a hybrid model.

离散元法和有限元法等数值计算方法各有其优势，同时也都存在不足之处：离散元法适于处理由连续介质向非连续介质转化的破坏问题，但对于连续体计算结果精度不高；有限元法适于预测材料破坏的区域，但难以直接用于计算脆性材料破坏过程，因此将两种方法结合可以形成一种较好的混合模型。
