Abstract
The papers analysis the flow patterns for air flow around cubic-shaped buildings. Experimental and simulation data were compared for the flow problems with different scales. Geometry parameters for the models can be varied from 0.025 to 6 m, meanwhile the range of Reynolds number for considered data is from 104 to 106. The study proves that the problem is scalable one: this creates a foundation for running the lab-scale wind tunnel experiments.
