-If a surface is emitting (``blowing'') or removing (``sucking'') gas, the flow normal to the surface disrupts the thermal boundary layer. Blowing tends to decrease the heat transfer coefficient while sucking tends to increase it. Adding \ct{BLOWING=T} to the \ct{SURF} line will account for this effect, except for DNS simulations where empirical heat transfer correlations are not used. When \ct{BLOWING=T}, the heat transfer coefficient is adjusted as follows~\cite{Plate_blowing}:
