The model established in steady state presents an exponential solution that is used, together with the Tau Method, to get a spectral approach of the solution of the system of partial differential equations associated to the model in transient state.engTau methodPartial differential equationsAir strippingVolatile organic compoundsbook part10.1007/978-90-481-9884-9_26
