Özet

The viscoelastic e®ects on the double di®usive oscillatory °ow in a °uid-saturated porous layer are investigated. A modi¯ed Darcy–Oldroyd-B model is used to characterize the non-Newtonian °uid behavior °ow in a porous layer. Analytic solutions of the dimensionless governing equations of °uid °ow are obtained and the e®ects of the °ow parameters on temperature, concentration, velocity pro¯les, skin friction and rate of heat transfer are discussed and shown graphically. It is interesting to note that skin friction increases on both channel plates as injection increases on the heated plate. Increase in the strain retardation parameter is to decrease the °uid velocity, while an opposite trend is noticed with increasing stress relaxation parameter. The study reiterates that the consideration of viscoelastic °uid is very important in proper considerate of oscillatory °ow in double di®usive °uid systems.
