### A High-Rise Building in City Blocks

02/10/2021

000304

The verification example describes the steady-state flow around a high-rise building in city blocks (scaled model). The example is given by the Architectural Institute of Japan (AIJ). Chosen results (velocity magnitude) are compared with the measured values.

### Flow Around a Simple Group of Buildings

06/04/2021

000306

The verification example describes wind loads in several wind directions on a model of a group of buildings. The model consists of eight cubes. The velocity fields obtained by the RWIND simulation are compared with the measured values from the experiment. The experimental data are measured using a thermistor anemometer in the wind tunnel.

### Drag Force on a Sphere

000300

A sphere is subjected to uniform flow of viscous fluid. The velocity of the fluid is considered at infinity. The goal is to determine the drag force. The parameters of the problem are set so that the Reynolds number is small and the radius of the sphere is also small, thus the theoretical solution can be reached - Stokes flow (G. G. Stokes 1851).

### Wind Pressure Loads on Buildings in Tandem Arrangement

02/18/2021

000305

The verification example describes pressure loads on the walls of buildings in tandem arrangment located at ground level. Buildings are simplified to rectangular objects and scaled down while maintaining elevation ratios. The pressure distribution on the walls of the model of a medium-high building was conducted by experiment. Chosen results (pressure coefficient Cp) are compared with the measured values.

### Wind Loads on an Isolated Building

02/09/2021

000301

The verification example describes the steady-state flow around an isolated building (scaled model).The example is given by the Architectural Institute of Japan (AIJ). Chosen results (velocity magnitude) are comparedwith the measured values.
