I am currently at my last MSc year in Chemical and Process Engineering (Italy), and our last course on Industrial Chemistry has a mandatory pre-exam exercise which reads:
Find an existing, published research paper in the field of Chemical Engineering and try to autonomously replicate its results (plots, data, equations et similia).
My chosen paper X was published in the Industrial & Engineering Chemistry Research journal, and I suppose it passed peer-review. X shows the application of a new algorithm to a chemical reactor with a given physical model.
However, after my revision and replication trial, I found that using their same model, I do not obtain the paper results. There is no presence of replication error by me, since I checked every passage with the TA.
The same TA pointed out flaws (of fundamental nature, for example F = mv instead of F = ma) in the model, and once corrected allowed me to obtain the results shown in the paper.
I do not think it was a overlook error, since the same reactor model was used in X and two cited sources of X. I want to inform of this error, but I do not know what to do now.
