- Abstract
In this investigation the finite volumes method was used to numerically simulate the thermo-fluid-dynamic behavior of air in an air conditioning distribution system. The mathematical model that-governs the behavior of airflow in the distribution duct was described by means of applying a turbulence or closure model. For this purpose k-ϵ, RNG k-ϵ and Reynolds Tensions models were used individually. Three cases were simulated and the results obtained from these simulations indicate that the k-ϵ model shows a better numerical behavior in the simulated problem, generating smaller residues in the flow variables and a reduced computing cost.
