Boundary Layer Resistance and Temperature Distribution on Still and Flapping Leaves: II. Field Experiments

J Y Parlange et al. Plant Physiol. 1972 Jul.

Abstract

The forced convection of heat from reed (Phragmites communis) leaves was observed in their natural environment. The leaves were painted with liquid crystals, which displayed or indicated their temperature without any interference with natural air flow. Temperature differences as large as 15 C were observed between the leading and trailing edges of the nontranspiring, painted leaves. The turbulence of the natural wind decreased the boundary layer resistance around the leaf to about 40% of the resistance in a laminar steady wind.
