| Abstract | ||
| A numerical study of two-dimensional turbulent buoyant rcirculating flow within mechanically ventilated rooms is reported. The study involves the solution of elliptic partial differential equations for the conservation of mass, momentum, energy, turbulent energy and its dissipation rate in a finite difference form. These equations were solved together with algebraic expressions for the turbulent viscosity and heat diffusivity, using (K-ε) turbulence model. A modified version of a two-dimensional elliptic computer code was used to simulate the complex flows inside a slot-ventilated room. The present study demonstrates that the flow behavior depends on several parameters, such as airflow rate, size and temperature of the heated obstruction. Each of these parameters was modeled separately to understand their affects on the airflow characteristic inside ventilated room. | ||
