This paper presents a numerical simulation based on computational fluid dynamics (CFD) method on the enhancement of natural ventilation in an industrial workshop with heat source induced by solar chimney (SC). Four types of SC were designed to attach to the top and southern roof of the workshop. Realizable k-ε turbulent model and DO (discrete ordinate) radiation model were used to calculate the air...
W pracy poruszono problem zmian w przepływie powietrza powstałych w wyniku rewitalizacji terenów poprzemysłowych zlokalizowanych w centrum starego miasta. Wprowadzenie nowych budynków ma wyraźny wpływ na warunki klimatyczne zarówno w skali miejskiej jak i lokalnej. Budynki blokują przepływ powietrza wnikający do miasta i osłabiają wentylację. Z drugiej strony w gęsto zabudowanych strukturach miejskich...
The fresh air intake of the hotel kitchen that air flow is introduced from the ground is investigated by the approach of numerical simulation. The results show that the proportion of fresh air intake from the ground is 8%~13%. At this time, the distribution of temperature is uniform relatively. And the environment of common kitchen is comfortable comparatively.
