Abstract

Temperature, relative humidity and air velocity profile inside a structure was simulated using computational fluid dynamics (CFD) software and was verified based on the actual measure parameters. Each setup was composed of the same material and was subjected under the same environmental conditions that may effect the behavior inside the structure. A total of 200 iterations were done and the domain material is air at 20°C and 1 atm. For the relative humidity characterization, the inverse distance weighted interpolation was used to interpret the parameters obtained at different point locations in each of the three structuresResults obtained were subjected to statistical analysis wherein no significant difference was exhibited among the three setups. For the air velocity profile, the initialized value equal to 17.22m/s incoming air produced the highest value at setup C. The temperture profile, on the other hand, varies depending on the height at which data was taken but results obtained showed no variations among the three setups. These proved that CFD software is important tool that can be used in the design of structures from small scale to large scale. Actual data was comparable to the result obtained using CFD.
