An oriented-design simplified model for the efficiency of a flat plate solar air collector [PDF]
, 2010 In systems design, suitably adapted physical models are required. Different modelling approaches for a solar air collector were studied in this paper. First, a classical model was produced, based on a linearization of the conservation of energy equations.
