Virtual chemical kinetics mechanisms are a new methodology for representing detailed mechanisms in applications where the size of the mechanism is limited (such as in CFD simulations where computational time is one of the main aspects to be evaluated). However, despite having the same objective, the obtainment, possibilities and final size of the mechanism are the big difference. A virtual mechanism is nothing more than a small kinetic mechanism whose species (here called virtual) and reactions have been optimized to represent a detailed mechanism (or some result arising from it). In this way, super accurate solutions can be obtained with mechanisms with a size comparable to global mechanisms. Its application is still limited due to how recent its development is compared to techniques such as mechanism reduction, however, its application in CFD has shown excellent results, as can be seen in several works.
