Sorry for my delay. There are so many situations.
I was finished the changing of the head geometries and sent those to Nam Keun before I left. I think Nam should start doing the simulations. Hope I could get the new results soon.
I will read your updated MS and try to provide my parts as soon as I could. I have some questions about the reviewers’ comments, but I think I should read the new MS first and may ask questions together.
Although I am pretty so I will bother you during the Christmas and New year, I still wish you will have a great Christmas and happy new year.
Best regards,
