Natural ventilation in a lege space with heat source: CFD visualization and taguchi optimization

Louvre-equipped generic enclosed (LEGE) space with heat source and guiding vents is commonly seen in many buildings, transfer equipment has plenty of practical applications. In the current work, natural wind- driven convection a LEGE system mono-centric under five louvre configurations different wind speeds are analyzed. The walls assumed adiabatic, introduced at centre levels heating range 100 400 W/m2. placed an ample rectangular to generate flow conditions. efforts conducting several experiments reduced by applying Taguchi method Anova used rank based on responses from CFD simulations. Firstly 3D steady RANS equations solved using Finite volume approach where RNG k-ω model was chosen for turbulence modelling. Nusselt number temperature were noted down as each case. Secondly, percentage contribution factors optimum experiment explored ANOVA technique. results reported contours velocity vectors inside enclosure, disclosing air circulation design configurations. Results show that louvres position had maximum 5 percent effect than other factors. From method, around 80%.
