lumped modelling meaning in English
集中模拟
Examples
- Development of twelve - lumped model for product distribution in thermal conversion of heavy oil
12集总重油热解反应产物分布模型的开发 - Also , one overall tar - cracking model was erected for comparison with the five - lump model
文中又进行了焦油整体转化模型的构建并将其结果与五集总模型进行对比。 - The overall cracking model was constructed on the basis of the kinetic models of each lump . this five - lump model was used to simulate the cracking process of tars from different sources and under different cracking conditions , and good results were achieved by comparison with experiment data
利用实验数据拟合得到各集总转化的动力学参数，并以此构建各集总转化过程的动力学模型和整体焦油转化过程的动力学模型，并取得了良好的效果。 - The validation of the programs is verified by the good agreement between the simulation results and experimental results in the single - stage compression system . it is also verified that only a qualitative analysis can be obtained using the one - dimensional unsteady lumped model ; but the one - dimensional unsteady stageby - stage model is more suitable for actual compressor operating conditions and can serve as an effective analytic tool for studying the post - stall behavior and improving recoverability of compression systems
判明了一维非定常总体模型只能定性的分析压缩系统的过失速性能，在定量的分析上存在着一定的局限性；而一维非定常单元容积模型更能反映压缩系统实际情况，从而为研究压缩系统的过失速性能和改善压缩系统的失速可恢复性提供了有力的工具。 - For practical purpose , an one - dimensional unsteady lumped model and a onedimensional unsteady stage - by - stage model , which are able to describe the dynamical post - stall behavior of compression systems , are derived firstly and then solved using the numerical methods to analyze the post - stall behavior and recoverability of compression systems . on the basis of characteristics of digital simulation of unsteady flow , the program for one - dimensional unsteady lumped model has compiled and tested under visual basic 6 . 0 environment completely . while the program for onedimensional unsteady stage - by - stage model has compiled and tested under foitran / visual basic mixed - language environment , which part of calculation is accomplished by fortran language
根据非定常流数值模拟的特点，通过可视化编程方法，用visualbasic6 . 0编写和调试了一维非定常总体模型的数值模拟程序；用visualbasic6 . 0制作界面，以fortran作为后台计算程序，编写和调试了一维非定常单元容积模型的数值模拟程序，成功地实现了vb与fortran的连接；使得数值模拟程序的界面友好，操作简单。
