Some instructors prefer the citation style used by the Journal of Fluid Mechanics (JFM). When they say, “Use the author/year style” for citing work, they may mean this or maybe APA style. Be sure to double check.
The JFM actually encourages its authors submitting articles to deploy Latex, which we will not address here. If you are submitting an article to JFM, follow its guidelines for authors.
In our CHEC pages, you will find how to cite in-text and how to format your Reference page without deploying Latex.
