Numerical and experimental study on flow and diffusion field in room.

Turbulent flow fields of velocity and diffusion in several types of mechanically ventilated rooms are precisely analyzed both by model experiment and by numerical simulation based on the k-s two-equation turbulence model. The detailed analyses of contaminant diffusion by simulation make it possible to comprehend clearly the structures of velocity and diffusion fields in rooms. The flow fields in such rooms, as analyzed here, are mainly characterized by the inflow jet and the rising streams around it.

Demand controlled ventilation systems for dwelling-houses of the future.

The functional and technical requirements which have been set for ventilation systems in dwelling houses of the future will result in ventilation systems featuring trouble-free and demand-controlled operation. This paper discussed the functional requirements and technical solutions of such ventilation systems.
