Web1 de jan. de 2003 · Similar to the smooth case, k is overestimated around the hillcrest by the standard k–ε, and this fault is corrected by the two revised k–ε models. As will be discussed later in detail in Section 3.2.3 , it is clearly observed that change in position of the separation point leads to the change in reattachment length (smooth and rough cases). Web30 de mar. de 2012 · On the upwind regions of the blocks, the wind is relatively weak in all cases. These weak regions are caused by the flow stagnations due to the collisions between the approaching flows and the downward flows from the upwind faces of the front buildings at ground level.
