Numerical computation of 3D heat transfer in complex parallel heat exchangers using generalized Graetz modes

We propose and develop a variational formulation dedicated to the simulation of parallel convective heat exchangers that handles possibly complex input/output conditions as well as connection between pipes. It is based on a spectral method that allows to re-cast three-dimensional heat exchangers int...
