Abstract
This paper presents the results of an experimental investigation performed at an open circuit boundary layer wind tunnel carried out with the purpose to evaluate the performance of a solitary "Fish-plan shape" building model for various angles of wind incidences with a mean wind velocity of 10 m/s and turbulence intensity of 12%. Mean pressure coefficients of all the faces are calculated from pressure values for each direction of wind incidence and pressure contours are plotted and explained in detail for all faces. Detailed analysis of peak and average mean pressure coefficient for each face is carried out. From the present experiment, it is observed that at 00 wind incidence face-value of the windward face is lesser than for the standard square model at IS 875 (Part 3) 2015. The study also presents higher magnitudes of peak suction and pressure coefficients at skewed angles of wind incidences i.e., 300, 600, 1200, and 1500 due to stagnation of fluid near the adjacent edge of depressed exposed faces. The magnitude of the overturning moment in across wind direction is dominating the overall behavior of the model due to the unsymmetrical cross-sectional shape of the model in across-wind direction. The orientation of the building at 900 to wind incidence should be avoided due to the peak magnitudes of CMD, CML, and CMT as compared to other wind directions.
