Two dimensional analysis of low pressure flows in the annulus region between two concentric cylinders [PDF]
SpringerPlus, 2016 A numerical simulation of the steady two-dimensional laminar natural convection heat transfer for the gaseous low-pressure flows in the annulus region between two concentric horizontal cylinders is carried out. This type of flow occurs in "evacuated" solar collectors and in the receivers of the solar parabolic trough collectors. A finite volume code is
