Summary on Grant Application Form
Traditionally, unsteady computational fluid dynamics (CFD) has focused on simulation of the time dependent Navier-Stokes equations where increases in computational power over time have permitted significantly larger simulations to be performed, with concomitantly larger volume of data as the outcome. One of the major issues facing the CFD analyst is the question of how to assimilate, analyse and apply this great wealth of data. One technique to help interpret the data is the application of stability and bifurcation analysis in order to understand the dominant linear instability of the flow problem. BiGlobal stability analysis is the numerical determination of the linearised flow stability around a two-dimensional basic flow state which in general may occur in a complex geometry and is the natural extension of the classical Rayleigh/Orr-Sommerfeld equations. The outcomes of flow stability analyses are particularly sensitive to the accuracy and resolution of the underlying numerical algorithm and spectral/hp element methods unit the geometric flexibility of finite element or volume methods with the high accuracy of global spectral methods. The focus of this project is to extend existing BiGlobal stability analysis technique to incorporate a perturbed threedimensional base flow thereby permitting a wider range of problems of greater engineering interest to be considered. Further we proposed to extend the application of these technique to an ongoing project to understand the transition to turbulence of pulsatile flow in a stenotic channel of interest in biomedical flow problems.
