Physics of diffuse ventilation - buoyancy convection performance

Sted

København og omegn

Diffuse ventilation is a novel type of ventilation where the fresh air is supplied over a large (ceiling) surface. High-impulse inlet jets, which would otherwise generate draught sensations, are avoided, ducting is saved, the energy consumption is lowered and in general the adabtability of the ventilation system to accomodate different types of load situations is increased.

However, the functioning of diffuse ventilation is ill-understood because it relies on natural buoyancy forces from the thermal sources in the room rather than forced convection from the fan. The project should investigate in extensive detail through CFD simulations and/or experiments how buoyancy affects the mixing and stratification and the performance of diffuse ventilation  in different scenarios, e.g. different floor plans, ceiling layout, strength of thermal sources, inlet temperature etc.

It is envisaged that the performance can be generalized through a study of Archimedes number and a design guideline be developed using the empirical data.

For an experimental project, two master students are preferred.
