Induced Buoyancy In Inclined Solar Chimney For Natural Ventilation

A 2-D plane, steady, incompressible, turbulent flow field developed by natural convection inside inclined solar chimney at different inclination angles ranging from (30o to 90o), heat fluxes from (100 W/m² to 500 W/m²) and chimney thickness(0.1, 0.2 m) chimney is investigated numerically. It is foun...

description A 2-D plane, steady, incompressible, turbulent flow field developed by natural convection inside inclined solar chimney at different inclination angles ranging from (30o to 90o), heat fluxes from (100 W/m² to 500 W/m²) and chimney thickness(0.1, 0.2 m) chimney is investigated numerically. It is found that maximum air temperature and maximum volume flow rate was 101.7oC, 306.3 m³/h respectively at heat flux,500 W/m2; inclination angle; 90o and chimney thickness; 0.2m. Maximum outlet air velocity was 0.488 m/s at chimney thickness; 0.1m, heat flux; 500 W/m2; and inclination angle; 90o. Increase in heat flux, inclination angle and chimney thickness leads to increasing of volume flow rate. Increase in chimney cross-sectional area leads to decrease in air velocity and increase in volume flow rate
