In this Study, the Numerical study has been completed to measure Pressure Coefficients on rectangular gable roof buildings in tandem arrangements by ANSYS-CFX Package. There was a major effect of change in roof angle (α) of both buildings as 10˚, 15˚, 20˚ for constant Height Ratio (H2/H1) of Principal Building to Interfereing Building with the change in Span Ratio (S1/S2). The spacing between two buildings is 1.5 m. The Numerical Simulation is carried out by Shear Stress Transport (SST) turbulence model. And also study the effect of different roof angle of both buildings, in which roof angle (α2 = 15˚) of tall building and roof angle (α1 = 10˚, 15˚, 20˚) of the small building is studied. From these study, comparison is done of PCOE between same roof angle and different roof angle for single span ratio. A Measure effect is due to change in roof angle (α) on Leeward Roof – 1, Leeward Wall – 1, Windward Wall – 2, Windward Roof – 2, Leeward Roof – 2. After the Simulation of all models, the comparison of PCOE of different roof angle for single span ratio is done. Numerical Simulation has indicated the importance of the span ratio and roof angle.
