Pressure-exerted steady laminar flow of an incompressible fluid along a porous parallel-walled channel with an impermeable wall.
Due to the two-dimensional configuration of the channel, relation (3) justifies the existence of the stream function I i whose definition is given by the following relations: HT <math display="block" overflow="scroll" xmlns="http://www.w3.org/1998/Math/MathML"><msub><mi>V</mi><mi>x</mi></msub><mo>=...
