Performance of universal limiter for QUICKEST scheme
Abstract
Application of unlimited QUICKEST scheme to solve advection-diffusion equation excites wiggles in the vicinity of abrupt gradient changes. When universal limiter is utilized to overcome these difficulties, the accuracy is degraded. The cause of this loss in accuracy is identified and a new strategy is proposed as a remedy. Numerical experimentation shows that modeling of advection-diffusion following the proposed strategy is nonoscillatory and highly accurate.
