Abstract A dual-source model that solves the energy balance over vegetation and soil separately can be inverted to obtain the roughness length for heat z0h of a single-source model. Model parameters for the dual-source model were taken from previous analysis of data from a sparse canopy in semiarid terrain. In these circumstances, the value of z0h, is shown to be dependent on the humidity deficit, the available energy, the vegetation fraction, and the surface resistance of the soil and the vegetation.

Numerical simulation of temperature field on friction stir welded 7022 aluminum alloy was studied in this paper. A new dual-source model has been designed and applied to investigate the variation of temperature field over time. Result shows that temperature of the nodes along the welding line increased at first and then decreased, the highest nodal temperature of 524°C presents at the ending position. Temperature of the nodes perpendicular to the welding line rises rapidly when the source arrived and falls rapidly when it left, and then cools to room temperature linearly when the source is removed. Simulative result predicts large temperature difference on the plates, and thermal pretreatment should be conducted before welding.
