Modelling of the coupling hydrodynamic transfer for a gas–liquid countercurrent ow on a wavy surface
نویسندگان
چکیده
This paper concerns laminar countercurrent gas–liquid ow over a wavy wall column, in the case of a falling liquid lm. The modelling concerns the coupling of hydrodynamic and heat and mass transfer for an absorption as an example of application. The falling liquid lm interacts, through the free interface, with the gas phase. The wavy surface generates particular hydrodynamic conditions with the presence of a vortex in both phases. The consequence of these vortices is an increase of transfers compared to the smooth wall.

Carbon dioxide capture is a key issue in climate change mitigation. For decades the removal of carbon dioxide has been an essential step in many industrial processing operations such as the synthesis of ammonia, natural gas purification, and oil refining. In this study, a rotating packed bed has been designed for absorption of carbon dioxide from an air stream. The rotating packed bed is a comp...

An experimental and numerical study of free convection heat transfer from a channel consisting of a vertical sinusoidal wavy surface and a vertical flat plate has been carried out. The vertical wavy surface was maintained at a constant temperature, while the flat plate is adiabatic. A Mach-Zehnder Interferometer was used to determine the local heat transfer coefficients of sinusoidal wavy surfa...
