[求助] 修改意见是小修还是大修?已经又返回去外审了,不懂!求教!已有6人参与

请教各位,我的稿件之前已经修改过一次,第一次给的修改意见较多;这次又叫我修改第二次,下面为编辑发来的修改意见,这次不知道是大修还是小修;两次修改回来的状态都是revise,看不出大修还是小修;可是这次修改后,实际上自己修改的地方不多,提交后编辑又送外审了;请问大家我这种情况最终录用的概率有多大啊?

Dear Dr.*******

Reviewers have now commented on your paper. You will see that they are advising that you revise your manuscript. If you are prepared to undertake the work required, I would be pleased to reconsider my decision.  

For your guidance, reviewers' comments are appended below.

If you decide to revise the work, please submit a list of changes or a rebuttal against each point which is being raised when you submit the revised manuscript.
Your username is:

Reviewers' comments:

Reviewer #1: The paper revised substantially according to the reviewers' comments. The bubble driven flow is difficult to model as the authors claimed, and a simplified model is applied in this work. Actually, there are progresses on the bubble driven flow work in the literature that can be referenced:

Kaiyu Zhang, Yuqing Feng, Phil Schwarz, Zhaowen Wang and Mark Cooksey, Computational fluid dynamics (CFD) modeling of bubble dynamics in the aluminum smelting process, Ind. Eng. Chem. Res., 2013, 52 (33), pp 11378-11390

Y.Q. Feng, W. Yang, M. Cooksey and P. Schwarz, "Development of bubble driven flow CFD model applied for aluminium smelting cells",  The Journal of Computational Multiphase Flow, 2010, 2, 179-188.

Note that the bubble induced turbulence play an important role for alumina dispersion. The drag coefficient in ACD is different from the free rising region.

While it is ok to use a simplified model, at least the others' model development work should be fairly cited. Otherwise, the paper gives an impression that the authors want to hide their weakness, e,g. the bubble driven model is even not mentioned in their first draft.



Reviewer #2: Greatly improved paper since first version. Looking forward for following publications as the work presented in this paper is only the beginning! I hope you will also be presenting that work or even better some follow-up work at the ICSOBA 2014 conference in October: http://www.icsoba.info/icsoba-2014

On second reading, I think that there is even more physic involved than you are describing in your model! In order to solve the heat transfer model, you must also solve for the bath temperature (TL) yet you are not discussing about that at all. In addition to the heat exchanged with the colder alumina particles, the bath is gaining heat from the Joule heating and is loosing heat through the ledge, anodes and metal pad. I assume that you are not solving for the local variation of the bath temperature in your model? Yet, a local addition of cold alumina particles will significantly drop the bath temperature at that location. If the bath temperature is considered constant, please comment on the impact of that simplification on the alumina dissolution rate prediction. Even more important, the liquidus temperature (Tliq) depends on the bath dissolved alumina concentration http://www.peter-entner.com/E/Theory/ElProp/LiquTemp.aspx, you could compute Tliq locally as function of the
local dissolved alumina concentration, are you doing it? If not, please again comment on the impact of that simplification on the alumina dissolution rate prediction.  

First paragraph of section 3, it is still not clear how you add alumina particles. There is a feeding period of 144 seconds so every 144 seconds 7.2 kg of alumina particles are added to the cell. But this is not a continuous addition, clearly from figure 5 we can see that at time 10 seconds, no more particles are added. What is the mass flow rate of the alumina particles addition or the duration of the alumina particles addition at the beginning of the simulation?

You commented on the fact that "only" 0.063 kg of particles is felt at the end of the 144 seconds feeding cycle in the Model verification section. Clearly you cannot sludge a cell in a single feeding cycle, but at 144 seconds per feeding cycle, that represent 600 feeding cycles per day so 37.8 kg of sludge accumulation per day. Without back feeding, this sludge will keep accumulating day after day!

小修,我看没啥问题了

请问你怎么看出是小修的?这种情况,两个都要送外审吗?第一个人感觉不用再送了吧,现在只收到一个人已经接受审稿。因为第二个人还有迷惑,是不是只送第二个再外审?
科研你行的加油
