Are there techniques for interpreting practical viability of some method?
That is, if one comes across some mentioned technique, then is there some way to gauge, how much prevalence it has for practical usage? Some theories may stay at a theoretical level for some time, and they're perhaps not a good use of time for someone, who is interested in usable techiques.
Consider, e.g.:
https://www.amazon.com/Boltzmann-Application-Engineering-Advances-Computational/dp/9814508292
With these coverage LBM, the book is intended to promote its applications, instead of the traditional computational fluid dynamic method.
Are there e.g. particular keywords to search for in journal archives or something?
