Future Aspects of the Study 61

Based on the results obtained from the current study, it is proposed that the investigation of downburst flow behavior should be done at more h/D and x/d ratios for different domain sizes. This can be adopted by different the downburst size which has been done in this thesis, or by different the height of the domain in which the flow is simulated.

Transient simulations, effects of ground roughness using more accurate turbulence models can be considered in the future study. More experimental work using facilities like WindEEE (Wind Engineering, Environment and Energy) Dome is to be done for validating the numerical data.

The surface pressure coefficients’ discussion carried out in this thesis was limited to mean values and considered only simple geometry. In the future, peak values and more complex geometry can be considered. Further work is required for structures placed at more diverse radial locations with respect to downburst center and also exposed to different downburst sizes.

The last aspect investigated in this thesis was the comparison of surface pressure

coefficients obtained from the cube subjected to downburst and ABL flow. It was found that downburst case gave considerably higher pressure coefficients when compared to those obtained from boundary layer case. But, as mentioned in Chapter 4, the pressure coefficients have been extracted by normalizing it with the velocity magnitude obtained at the building height. For the building subjected to downburst flow, different velocities are obtained along the roof surface of any building; hence, the critical velocity value to obtain the pressure coefficients is debatable. More insight is required as to how the pressure fields at building height for downburst flows are measured which are further used to obtain the structural forces and moments.
