- This paper employed a new staggered grid discretisation method to solve a linear stability system using MATLAB code to predict asymmetric and non-asymmetric instability in the wide gap between concentric rotating cylinders. The paper is significant because it provides a unified solution for both axisymmetric and non-axisymmetric flows, using numerical models. The unified solution is of fundamental interest for a more complete understanding of the instability theory in the design of relevant engineering devices with high societal and economic impacts, such as the annular flow in oilwells, flow in submerged pumps for water wells, and flow in vertical turbine pumps.
