Global stability analysis of the natural convection between two horizontal concentric cylinders
Serrano-Aguilera, Juan José; Blanco-Rodríguez, Francisco José; Parras-Anguita, Luis (ELSEVIER, 2021-06)
In this investigation, the 2D flow between two horizontally positioned concentric cylinders (gravity per- pendicular to the axis of the cylinders), where the inner cylinder is kept at constant temperature Ti higher than ... -
Global stability map of the flow in a horizontal concentric cylinder forced by natural convection.
There are a large number of studies in the literature on natural convection in the annulus between horizontal concentric cylinders. However, not many publications dealing with global stability analysis in this kind of flow ... -
