Abstract

The term mixed convection (MC) is used to describe the process of heat transfer in fluids where forced convection (FC) and thermal convection (TC) coexist. Mixed convection is an often occurring flow condition e.g. in the oceans, atmosphere, indoor climatisation or industrial processes and applications. In many flow situations convection is the prevalent transport mechanism of heat whereas the heat transfer strongly depends on the dynamics of the largescale structures. In this study we investigate the formation of large-scale circulation (LSC) in mixed convection and the influence of the dynamics of the LSC, also known as mean wind, on the heat transfer.

Document Type:Conference or Workshop Item (Speech, Paper)
Additional Information:Proceedings: It is a well-known paradox that although few scientists appear to favour publication of the proceedings of a Conference, proceedings are almost always published. In the case of European Conferences, the EUROMECH Council sees no necessity for publication of proceedings. In general, participants should be encouraged to seek separate publication of their contributions in scientific journals such as the European Journal of Mechanics A and B. For the ESMC it has been found convenient to publish all the invited lectures in a special issue of this journal.
