Title: My 50+ years journey from numerical analysis to computational fluid dynamics

Abstract: I will talk about how I started off in numerical analysis with deep interest in the accuracy of numerical solutions of partial differential equations with interest in applications to the Navier- Stokes equations that represent fluid flow phenomena. My journey started with elliptic differential equations in two dimensions and then expanded to the biharmonic equation and linearized versions of Navier- Stokes equations. I learned to compute on the old computing systems that required punched card input, and progressed to more modern systems including a foray into GPU computing. Eventually, I have been able to solve a variety of time-dependent problems and compare the numerical solutions with experimental and physical data.
