審稿意見該如何回答,reconsider my decision是啥意思?

請教各位,我有一篇稿件,審稿意見如下,編輯說 I would be pleased to reconsider my decision是什么意思?修改稿還要修回進行外審嗎,還是編輯自己會作決定?兩個專家提到的加一個bubble force,以目前的知識水平目前實在是做不出來,而且也沒看到有人做,不知道該如何回復(fù)啊。如果我實話實說,編輯會怎么處理呢? Dear Dr. XXX 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. Reviewers' comments: Reviewer #1: This paper studies the alumina dissolution process in alumina reduction cells using a computational modelling approach. The alumina dissolution determines the local concentration of alumina in an aluminium cell, and plays an important role in determining the cell performance. The topic and results are very interesting and novel. The only drawback is that the bubble driven flow is not considered in this paper. To my understanding, the alumina mixing process is dominantly driven by bubble induced flow, rather than the MHD force. It is better to state this in your revised manuscript. Reviewer #2: I agree that to my knowledge too it is the first paper on the full simulation process of alumina in a cell. Such a model is supposed to address both the sludge formation problem and the anode effect problem. You raise the sludge problem and the fact that at the end of your first and only feed cycle there is still 0.11 kg of undissolved alumina particle but there is no provision for sludge formation (particles crossing the bath-metal interface) and entering the metal in your model. You are acknowledging that the CO2 bubbles have an important impact on the bath flow yet you have decided to neglect that impact altogether. Obviously this means that the results presented in figure 4 due to the MHD flow presented in figure 3 is only a demonstration of concept not valid for industrial application. You are saying that you don't have access to enough computer resources to solve a fully coupled 4 phases flow by adding bubbles to your current model. I would argue that you should first solve a 2 phases flow that consider the MHD Lorentz force and the bubbles drag force on the bath flow. Second you should solve the TPPBM model without any coupling with the CFD flow solution obtained in the first phase as in my view that coupling has a negligible impact on the bath flow except in the 160 mm x 120 mm feeding area for the few seconds that you are actually feeding the particles to the bath. In order for your model to be able to predict anode effect problems, the model should be run enough feeding cycles to get away from your artificial initial uniform 2.5% dissolved alumina concentration in the bath and get to the quasi-steady-state dissolved alumina concentration distribution in the bath (of course using a bath flow that is considering the bubble drag force). Finally, under the current limitations of your model, I would far more interested to see more results in 3D around 1 feeder region. How fast are you adding your 1.8 kg of alumina particles in 1s, 2s 3s? In that region your fully couple CFD-TPPBM model is really ready for industrial applications, would it help alumina dissolution to add that 1.8 kg in 10s 20s? Minor revisions recommendations: -no need to write TAYLOR in capital letters in second page second to last paragraph -reference 22 was published in 2013 not 2010 -please specify the actual flow rate used in the presented results in the phrase: A total of 7.2 kg of alumina is fed ... at the end of the first paragraph of section 3. -the presented results gives the impression that this is only a 2D model, it would be nice to add a close-up figure showing the vertical alumina concentration and particles position at 1 feeder region about 10s to 20 s after feeding. Any particles reaching the bath-metal interface, if so at what speed? |
