I worked for a few months on simulating the magnetohydrodynamics of insulating spheres and found some novel relations and insights I have never seen in print during an extensive literature search. My supervisor advises to write one or two publications about this and I would be glad to, but for which journals? I could submit a paper about the fundamentals, many nice pictures and obtained correlations to the 'journal of fluid mechanics' or 'physics of fluids' or the like. It would be great to publish in such a widespread journal but it has quite the chance of getting rejected and if I understand it corectly that would probably results in a few months delay / more rejections. Would it be better to submit to a bit more low profile journal? As this would be my first publication, any suggestions, advise, tips, stories are welcome!
