Is the use of "for the first time" in the following sentence correct grammatically and conceptually? If it is not, kindly suggest ways to make it clearer.
The main goal of this study is to highlight the effect of the blade thickness on the entropy generation analysis of the Wells turbine for the first time.
Your example is grammatically OK, but if you need to emphasize "for the first time", I would write:
The main goal of this study is, for the first time, to highlight the effect of the blade thickness on the entropy generation analysis of the Wells turbine.
This creates a better flow. [topic][the fact it is the first time][goal]
