Sun intensity is different according to its angle of radiation. North and south or east or
west of a building will receive different solar intensity. The radiation also affected by the
inclination of the surface where sun radiates. Thus, the effect of the different
configurations is investigated. The radiation intensity for the collector and canopy in the
on-roof solar chimney is different since the material used is different which resulted in
different temperature. This difference in temperature will be a significant effect in
analyzing the output of the solar chimney. The methods and analysis are done using
Computational Fluid Dynamics (CFD) software such as GAMBIT and FLUENT. The
analysis was also done for three cases with different configurations. Case 1 consists of
Configuration 1 (trimmed-inlet) and Configuration 2 (flat-inlet). The configurations were
analysed with two options of temperature distribution, Option A (same temperature for
left and right side of roof) and Option B (different temperature for left and right side of
roof). Case 2 have two different heat transfer consideration for the collector either
conduction or convection and is analysed for three different inlet diameter. Case 3 is
solar-biomass integration chimney configurations. From the simulation particularly from
FLUENT, the outlet velocity is different for different geometry configurations and
operating conditions.
