| 1 | Mathematical simulation of radial heat transfer in packed beds by pseudohomogeneous modeling显示文摘Uniform flow regime and constant effective thermal conductivity inside packed beds are commonly accepted in the evaluation of the fluid dynamics and heat transfer in such systems.However,several authors have confirmed the presence of an oscillatory velocity profile caused by the effective contribution of porosity profile in the fluid dynamic behavior of packed beds,which directly influences the heat transfer inside the beds.This paper describes the application of a pseudo-homogeneous mathematical model for describing heat transfer in packed beds with oscillatory profiles of velocity and porosity,using a radius-dependent model for effective thermal conductivity k r.Several temperature profiles were obtained in a packed bed system with thermal source located on the wall.The simulated temperature and effective thermal conductivity obtained from simulations were compared with experimental data and calculation from a model based on uniform k r fitting.The results indicate that the proposed mathematical modeling was capable of better representing the heat transfer in the packed bed. | Rodrigo Béttega Marcos Flávio Pinto Moreira Ronaldo Guimaraes Corrêa José Teixeira Freire | 2011 | Particuology2011，9，2： | 2 |
| 2 | 改变进气门相位对进气充量的影响显示文摘活塞与进气门交互运动产生的压力波会沿整个进气管传播,这种压力波能适当增加进入发动机气缸的进气质量。进行了改变进气门相位的试验研究,目的是分析它对进气充量的影响。‘试验在一台1. O L,16气门、每缸?,个进气门的产品发动机上进行。先在气流试验台上进行模拟发动机进气流状况的初步试验,然后再在测功器上进行发动机试验。气流试验台测试结果显示,在300CaA范围内改变进气相位角能使进气质量增加。发动机台架试验的结果是在进气门比原来气门开启相位迟开7. 50CaA的情况下测得的。 | Pereira L V M Pires L B M Pinto A A 李慧萍 | 2005 | 国外内燃机2005，37，6： | 2 |
