This paper reviews the progress and challenges of problems related to the Oldroyd B model that are of current interest to the mathematical community, including existence results, flow stability, and understanding the asymptotics of the high Weissenberg number limit. Efforts and challenges in numerical simulation are discussed through examples such as extensional flow, flow past a confined cylinder, and locomotion of microorganisms in a viscoelastic fluid.
We review progress and open challenges for a number of problems related to the Oldroyd B model which are of current interest to the mathematical community. We discuss existence results for initial value problems and steady flows, flow stability, and the problem of understanding the asymptotics of the high Weissenberg number limit. We also discuss efforts and challenges in numerical simulation, exemplified by three problems: extensional flow in a four roll mill geometry, flow past a confined cylinder, and locomotion of microorganisms in a viscoelastic fluid.
