چکیده

Fluent, as one of the commercial CFD packages, the author discussed its application in greenhouse ventilation research. In the paper, the under problems would be expounded: in fluent what models will be used in greenhouse studying, and the details during in these models used, and the comparing of the same style models. The steps to solve the greenhouse problem also was expatiate in this paper, mainly including: how to abstract its physical models; how to define its compute domains; the factor should be considered in creating and meshing the geometry; the types of boundary condition, and how to give the boundary conditions, in this section, the author will take some instances to emphasize discuss; the selection of parameter in simulation, and a few of methods of post processing. At the last, the author introduced some even existing problem in simulating.

Natural Ventilation: Analysis of Indoor Airflow in an Assumed Cubic Building with Opposite Openings by CFD Investigations

The natural ventilation is an easy way to exchange the indoor polluted warm air with outdoor fresh air. The wind power injects outdoor fresh air into the building. A good indoor air current and subsequently a proper exhaust depend on the openings’ conditions and their situations. A serious architectural question is under what conditions of the openings the wind-cross ventilation can be effectiv...

Experimental study and application of computational fluid dynamics on the prediction of air velocity and temperature in a ventilated chamber

The shape of the air flow in the interior is heavily influenced by the air distribution system and the way air enters and exits. By numerically simulating flow by computational fluid dynamics, one can determine the flow pattern and temperature distribution and, with the help of the results, provide an optimal design of the air conditioning system. In this study, a chamber was first constructed ...

Simulation of Metro Train Fire in an Underground Station of Tehran Metro Line 7

In this research a fire scenario was simulated in one of the stations of the line 7 of Tehran's subway system. The Line 7 is under construction and the ventilation system is under design. Fire was set for a stopping metro train at the platform of the station. A 160 meter length eight-car metro train with the forth wagon on the fire was studied. The heat release rate is based on a quadratic f...
