Ubuntu,where freedom goes on

Right now,I'm just enjoying Southern Africa's wonderful landscape,where the Ubuntu takes me to.It feels like wondering in the kingdom of freedom.
Yes,I just installed the Ubuntu9.04 "Jaunty".
With no configured chinese IME,i just can write this article in English,but I would rather like to write like this.
There are some changes in today's release,but there are also something never change!They are what I called freedom.

Let's enjoy Ubuntu's principle in the following quote,which comes from "About Ubuntu" in the OS.

[quote]Ubuntu - Linux for Human Beings!

This section is an introduction to Ubuntu. It explains the Ubuntu philosophy and roots, gives information about how to contribute to Ubuntu, and shows how to get help with Ubuntu.

Thank you for your interest in Ubuntu 9.04 - the Jaunty Jackalope - released in April 2009.

Ubuntu is an entirely open source operating system built around the
Linux kernel. The Ubuntu community is built around the ideals enshrined in the Ubuntu Philosophy: that software should be available free of charge, that software tools should be usable by people in their local language and despite any disabilities,and that people should have the freedom to customize and alter their software in whatever way they see fit. For those reasons:

*Ubuntu will always be free of charge, and there is no extra fee for the "enterprise edition"; we make our very best work available to everyone on the same Free terms.

*Ubuntu includes the very best in translations and accessibility infrastructure that the free software community has to offer, to make Ubuntu usable for as many people as possible.

*Ubuntu is released regularly and predictably; a new release is made every six months. You can use the current stable release or the current development release. Each release is supported for at least 18 months.

* Ubuntu is entirely committed to the principles of open source software development; we encourage people to use open source software, improve it and pass it on.[/quote]
内容概要:本文详细介绍了使用COMSOL进行三相电力变压器温度场与流体场耦合计算的具体步骤和技术要点。首先讨论了变压器温升问题的重要性和现有仿真与实测数据之间的偏差,接着阐述了电磁-热-流三场耦合建模的难点及其解决方法。文中提供了关键的材料属性设置代码,如变压器油的密度和粘度随温度变化的关系表达式,并强调了网格划分、求解器配置以及后处理阶段需要注意的技术细节。此外,还分享了一些实用的经验和技巧,例如采用分离式步进求解策略、优化网格划分方式等,确保模型能够顺利收敛并获得精确的结果。最后,作者推荐了几种常用的湍流模型,并给出了具体的参数设置建议。 适用人群:从事电力系统设计、变压器制造及相关领域的工程师和技术人员,特别是那些希望深入了解COMSOL软件在复杂多物理场耦合计算方面应用的人群。 使用场景及目标:适用于需要对变压器内部温度分布和油流情况进行精确模拟的研究或工程项目。主要目的是提高仿真精度,使仿真结果更加贴近实际情况,从而指导产品设计和优化运行参数。 其他说明:文中不仅包含了详细的理论解释和技术指导,还提供了一些实际案例供读者参考。对于初学者来说,可以从简单的单相变压器开始练习,逐步掌握复杂的三相变压器建模技能。同时,作者提醒读者要注意单位的一致性和材料属性的准确性,这是避免许多常见错误的关键所在。
