伙伴们！有谁知道国内外哪些机构或者大神做过或者正在做船舶在碎冰中航行的冰阻力数值仿真研究…跪求…

感谢分享！！！:huahua:

@bestucan 好吧，谢谢。我再琢磨琢磨

大神如何让stl 导入 运行第一步blockMesh？
我一运行就报错

你这个直接在ICEM里面就应该能看出问题吧，在ICEM里面先看看网格质量之类的

@赵一铭 整个程序我用的SIMPLE算法，所以连续性方程改成了压力修正方程来求解压力，不能直接求解出密度，怎么办？

@cfd-china link text!![alt text]0_1492654992588_QQ截图20170420102158.png 这是这个文献上说的在固壁上的条件；还有一篇文献直接在壁面设置为0了link text0_1492655090308_QQ截图20170420101901.png

请教大家我想计算模型中某一条线上压力的平均值，能不能用表面积分里的面平均来计算?我看也能算出结果，但一条线上的面平均是咋算出来的？d049db0ca27374c3678ae7cb343985d1.JPG

The effective delivery of drug particles or agglomerates from blood vessels to tumour cells is a critical step for their effectiveness in treating the target tumour. This project aims to understand the particle-scale fundamentals in the transport processes by means of unique state-of-the-art numerical techniques. Of particular interests are non-spherical particles transports inside blood vessels, through vessel walls and inside tumour cells, agglomerates breakage, and the effects of key variables. The outcomes will help improve the understanding of underlying micro-scale physical processes that control nanoparticle drug delivery in basic terms, and then provide an effective tool for designing effective drug delivery to targeted regions of clinical importance.

The applicant is expected to have proven research skills including multiphysics modelling and drug delivery related experiments, research experience in drug delivery or biological process, and demonstrated track record of independent research for example published first-author research papers in high-impact journals.

谢谢，我刚把这个导入到程序中，但结果仍然不理想，解出得P'偏大，在修正速度时会导致速度变成负的，而且是进口速度得负几十倍，所以总感觉压力方程和速度方程不匹配，肿么破？？:crying:

这个是完全的数学统计问题。$\overline{u'u'}$就是$u'u'$的时间平均。。。u'v'也一样。这个商软是不是应该能直接输出出来？openfoam能直接输出出来。

这个啊，先排错，
看看是“只有20可以”，还是“数字小了才可以”。
比如试试19，21，试试200。

错误定的越准，描述才越准，也越容易搜到前人的经验

@李东岳 谢谢大神的解答:happy:

填坑，参考官方t13教程（没记错的话，反正题目有个stl，似乎只有这种方法）

不是很了解这个技术。

这个我已经解决了，是写代码算出接触点和旋转角度在gambit里直接生成的，很容易。

AS&T Outstanding Publication Award

AS&T's Outstanding Publication Award is awarded annually to one paper published in Aerosol Science and Technology (AS&T) without regard to publication date. The award recognizes papers that have had a significant impact on the field. Nominations should include a single letter and a citation of approximately 100 words. The letter is limited to three pages and may be signed by more than one person. The citation is a succinct summary of the significance of the paper, suitable for dissemination with the award announcement. Self-nominations are not permitted.

AS&T's Editor-in-Chief presents the AS&T Outstanding Publication Award at the annual AAAR meeting. It consists of a certificate for each co-author, one plaque to be used at the discretion of the co-authors, and monetary award of $2000. In addition, it is announced in AS&T along with the rationale for its choice.

AS&T Publications recognized by this award:

2016

Robert McGraw, Description of Aerosol Dynamics by the Quadrature Method of Moments

2015

Shih Chen Wang and Richard C. Flagan. "Scanning Electrical Mobility Spectrometer" Aerosol Science and Technology, *13*, 230-240 (1990).

理论上了解一些求解方法，软件没有用过 :chitang:

@昝磊 好像是做凝固，李喜老师那的:huahua:
