Abstract:In Reference 1, Johnson and MacKinnon consider two convection schemes. For ease of reference, call these QUICK(l/8) and QUICK( 1/6). The authors state that the QUICK(1/8) scheme is only O(h2) accurate when used (as originally intended*) as a finite-volume method, and that the alternative QUICK(1/6) scheme is O(h3) in a finite-volume formulation. In fact, exactly the reverse is true: the QUICK(1/8) scheme is O ( h 3 ) accurate in a finite-volume formulation, but only O(hz) accurate in a single-point (finite-dif… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
