October 16, 2014 Dear Dr. Szabó,

Please find enclosed our manuscript, “Mass flux distribution measurements and visualizations of a fluid sheet generated by a partially immersed dip-lubricated gear” by Gergely Kristóf and myself, which we would like to submit as a research article for publication in Periodica Polytechnica Mechanical Engineering. In our work, we explored the features of this elementary flow using laser sheet and flash visualizations, and a newly developed quantitative measurement apparatus.

The flow we investigated is a minimal model of lubrication in transmission gearboxes, an important industrial problem, and, referencing to our data provided in this work, it can become a standard test case to be reproduced by experimental, theoretical and CFD people. The presented quantitative measurement method is a cost-effective way to measure velocity fields in situations where optical techniques do not work, waiting to be applied on free jets, film breakups, atomizers, and a broad range of other two phase flows. Because of these reasons, we believe our findings would really appeal to the readership of Periodica Polytechnica Mechanical Engineering.

We look forward to hearing from you at your earliest convenience.

Sincerely yours, Zsolt Várhegyi, MRes
