Blended Wall Laws

The blended wall laws are intended to represent the buffer layer by appropriately blending the viscous sublayer and logarithmic regions. For momentum, Reichardt's law [18] is used:

(157)

where:

(158)

(159)

(160)

For temperature, Kader's law [16] modified slightly for the effects of wall roughness is used:

(161)

where:

(162)

and

(163)

where is the roughness function.
