Question

谁能帮我把下面这段文字翻译成英文的，一定要完整无错误的,急！！！

本文采用CFD方法对某轿车进行二维外流场的数值模拟，利用AUTOCAD软件，构建本轿车的1:2二维模型，导出与GAMBIT软件接口的sat格式文件，再导入前处理软件GAMBIT中生成外流场网格区域，接着在FLUENT中进行数值模拟计算，通过数值模拟计算得到轿车周围的绕流流场、压力场、以及尾流的流态显示，分析该轿车外流场的气流分离、涡流等分布情况。通过对该轿车的气动阻力特性进行分析，来研究该轿车的外形设计是否合理，本课题还简单的研究了选用不同的湍流模型及不同入口速度对数值模拟结果的影响。
额。。好像太难了，有没有英语专业的，救命啊！！！

Answer 1

就是几个月前的事儿。有一个小孩儿，他爸爸妈妈晚上都出去了，就他一个人在家。由于那个小孩儿也不信什么鬼呀神呀的，所以也不害怕。这就是“心里没鬼怕什么？”到了晚上十一点多了，他爸爸妈妈还没回来，他开始有点担心。结果一给他爸爸妈妈打电话，电话筒里传出来的，却是“您的的电话是空号，请查询后再拨······”那个小孩儿很害怕，就报了警。结果不知道怎么回事，他家的电话突然着火了。那个小孩儿大叫，往外跑，结果们也锁了。他绝望的看着墙壁。

“吓死我了！”那个小孩儿醒过来，发现自己在做梦。这是，一个女的拿来毛巾，给他擦了擦汗。然后那个小孩儿倒头就睡。正当闭上眼睛的那一霎那，回想起那个女的，突然想起那个女的没有眼睛，眼眶里是漆黑的，脸上也留着血，脸色惨白。他大叫一声：“啊！救命啊，快来人呀！”他开始往门外跑，结果门真的锁了，他去厨房拿起菜刀，就像那个女的砍去，结果菜刀把那个女的一截两半，然后那个女的有复原了。伸出指甲里都是血的手，向那个小孩儿抓去。

此时此刻，你千万别看你的后面，因为，用肉眼是看不到的！如果你不把这篇帖子复制发给3个人，凌晨四点，你将会死于非命······

Answer 2

Based on the CFD method to one car two-dimensional outflow field numerical simulation, using AUTOCAD software, constructing the car's 2-1 2 d model, deduce GAMBIT with software interface sat format file and then import processing software of the generation before GAMBIT outflow field grid area, then in FLUENT in numerical simulation, by means of the numerical simulation to get around the car around the flow field and pressure field, and the vibration of the flow visualization, and analysis the outflow field flow separation of cars, eddy current distribution, etc. Through the car's aerodynamic drag characteristics are analyzed, and to study the car appearance design is reasonable, the subject of the simple still choose different turbulence model and different inlet velocity to affect the results of numerical simulation.

Answer 3

This paper uses the CFD method on a car in two dimensional numerical simulation of flow field around, use AUTOCAD software, build the car1:2 two-dimensional model, derived with the interface of GAMBIT software sat file format, and then imported fore treatment software GAMBIT to generate the external flow field of regional grid, then in FLUENT is simulated by numerical simulation, calculated the car around the flow field, pressure field, and wake flow visualization, analysis of the external flow field of flow separation, eddy current distribution. Through the car's aerodynamic drag characteristics of analysis, to study the design is reasonable, the paper also simply studied using different turbulence models and different entrance velocity on the results of numerical simulation of the effect of.
