Pointwise boundary layer
WebThe boundary layer is the air flow that is closest to and in contact with the aircraft surface, as shown in the figure below. Aircraft boundary layer transitions. In the figure above, the boundary layer is laminar. This is indicated by the layers of airflow and is typically determinable by the Reynolds number --less than 500,000 for laminar ... WebSave time by computing your near-wall cell height for the boundary layer before generating your grid. The Y+ Calculator works in either SI or Imperial units and quickly resets to sea-level conditions. This utility is brought to you by Cadence Design Systems. ... Pointwise is now Cadence.
