Abstract EN
The external heat transfer of dams during construction is complex because such transfer is location specific and time varying.
An external thermal model is developed in this paper.
Five types of external heat flux are considered in the mathematical model: air-side convection, electromagnetic radiation, absorbed solar input, water-side convection, and surface insulation effect.
A method for extracting and classifying the external surfaces of dams on the basis of Boolean operations is proposed.
Heat transfer conditions can be automatically set up for each step according to the proposed method, and the method can be used as a preprocessing facility for finite element analysis.
A 285 m high arch dam in Southwest China is examined as a study case.
The model is implemented and found to correctly identify different types of external surfaces.
Simulation result agrees well with the monitored temperatures.
