Curvature‐compensated convective transport: SMART, A new boundedness‐ preserving transport algorithm
Philip H. Gaskell,A. K. C. Lau +1 more
TL;DR: A polynomial-based discretization scheme is constructed around a technique called ‘curvature compensation’; the resultant curvature-compensated convective transport approximation is essentially third-order accurate in regions of the solution domain where the concept of order is meaningful.
