摘要：

The fire-induced air flow in a ventilated tunnel with a local gas burner is investigated experimentally and numerically. To simulate the transient three-dimensional turbulent buoyancy flow. calculations employ the turbulence k-epsilon model which is modified to take account of the effects of the mean streamline curvature (MSC). General curvilinear coordinates are generated for the computation. The prediction is compared with the experimental data and shown to be in reasonable agreement except the region close to the heat source. The present model can also be used to predict the location of the leading edge of the heated air flow.
