Variation of flow within the MUST building array

Numerous 2D and 3D sonic anemometers were deployed in, above, and around the Mock Urban Setting Test (MUST) array. MUST consisted of a 10 by 12 aligned array of containers, each 12.2 m long, 2.42 m wide, and 2.54 m high (H). The array was located in Utah’s West Desert at US Army Dugway Proving Grounds in relatively flat terrain surrounded by low scrub brush. Mean and fluctuating velocity along the array at a height of 0.8 H with corresponding upstream velocity profiles are presented. The data exhibits some unexpected behavior. The flow within a channel of the array nominally aligned with the mean wind speed was found to increase with downstream distance after an initial deceleration as the flow enters the array. This data contradicts a monotonic decrease in velocity with downstream distance found in physical and computational models.
