Title Efficacy and potential use of cyclonic turbulance in ventilation systems
Original title Wstęp do badań nad przydatnością i możliwościami wykorzystania wiru powietrznego w technice wentylacyjnej [in Polish]
Bibliographic information 1981, Vol.31, No.108, p.13-30. Illus. 6 ref.
Abstract Report on laboratory studies to determine the characteristics of cyclonic turbulence in a closed space and its potential application to the design of ventilation systems. The studies covered velocity, pressure and temperature distribution in relation to turbulence induction procedure, the effect of gas emission point, specific gravity and system positioning in relation to gravity field on gas concentration distribution, and on installation dynamics. The results show the value of turbulence ventilation, but research is still required on turbulence resistance to various disturbing effects (mechanical obstacles, fluctuations in volumetric airflow in the ventilation system, etc.).
