This study examines the validation and precision of essential parameters, including temperature distribution and nitrogen oxide (NOx) emissions, at the outlet of a gas turbine combustion chamber through high-fidelity Reynolds-Averaged Navier-Stokes (RANS) CFD simulations.
Some kinds of flat roofs with low height of ventilated air gap have certain problems with thermal and moisture regime. The lower surface temperatures of internal constructions in the air gap of roof and presence of hot and moist air in the air gap from indoor environment of building causes condensation of water vapour at the cold surfaces of roof internal constructions. This kind of flat roofs was used in our country at the end of the 20th century. The used construction of flat roof is split in two parts. Between them is ventilated air gap. The thickness of the air gap is 150 mm.
