NUMERICAL MODELING OF THE SPIRAL PLATE HEAT-EXCHANGER

The spiral plate heat exchanger (SHE) is widely used in plenty of indu strial services in full counter current flow liquid-liquid heat exchan ge. We have produced a thermal modelling of the heat exchanges in both steady-state and time dependent cases with 2D spiral geometry, allowi ng computation with different materials, forced convective heat transf er models in turbulent flow and geometrical parameters options. We wil l display here some results in steady-state conditions in order to imp rove the exchanger performances.
