Computational simulation of indoors temperature field: comparative study between the application of short and long wind-catch

Aiming to study the temperature field changes, the House VI project was checked. This house is located in Vila37, Rio de Janeiro, Brazil, a dead-end small street with only one inlet/outlet. In the houses of Vila37, the indoor ventilation is restricted to the facade windows. Giving the impossibility of introducing cross-ventilation in a traditional way, a short wind-catch was previously added with positive results; therefore, simulations with long wind-catch are being carried out. The analysis started by solving the air-circulation problem by using a finite element method and after, with the wind fields added, the heat transfer problem was analysed. The results obtained were evaluated and compared with the previous ones.
