WebBy default, ANSYS FLUENT treats walls as zero thickness presenting no thermal resistance to heat transfer across them. If a thickness is specified for walls then the appropriate thermal resistance across the wall … WebEnhanced wall treatment is a near-wall modeling method that combines a two-layer model with so-called enhanced wall functions. However, the restriction that the near-wall mesh must be sufficiently fine everywhere might impose too large a computational requirement.
