Transition modeling is a research area within the field of computational fluid dynamics (CFD) that focuses on understanding and predicting the transition of flows from laminar to turbulent behavior. This transition can occur due to various factors such as changes in flow velocity, pressure gradients, or geometric configurations. By developing accurate models for transition, researchers aim to improve the prediction of flow characteristics and performance in engineering applications such as aircraft design, automotive engineering, and gas turbine design. Transition modeling typically involves the use of empirical correlations, turbulence models, and advanced numerical methods to simulate the complex flow phenomena involved in the transition process.
