- Additional information
- This paper reveals how to optimise numerical stability more generally. Thus we explain performance issues observed in academic studies and commercial/industrial solvers and offer a remedy. This brings the opportunity for improved computational efficiency and accuracy and high Reynolds number flows, and also yields a numerical model for microscale flows - two of the most important areas of computational fluid dynamics. This work has been developed further or applied in 3 PhD completions (Mohammed (2019), Krastins (2020), Bu Sinnah (2020))
