It is considered that the fluid has small electrical conductivity and the electro-magnetic force produced is also very small. The flow is subjected to suction at the cold wall and injection at the heated wall. Under the Boussinesq's approximation, the governing equations are solved using multiparameter perturbation technique. The effects of pertinent flow parameters on fluid velocity, temperature, shearing stress, the rate of heat transfer is obtained and illustrated graphically. This study plays an important role in physiological, industrial and hydrological problems under suitable conditions.

The fluid is subjected to a transverse magnetic field and the slip velocity at the lower wall of the channel taken into consideration. A mathematical model (Walters liquid model B′) has been analyzed using appropriate mathematical techniques. Expressions for velocity, temperature, concentration, wall shear stress and rate of heat and mass transfer have been obtained. Variations of the quantities with different parameters are computed by using MATLAB software. The results are discussed graphically to measure the impact of visco-elasticity.

There is no external electric field imposed on the system and the magnetic Reynolds number is very small. To solve governing equations of the problem the perturbation technique has been used and the important properties of the overall structure of the motion are analysed. The influence of visco-elasticity on the fluid velocity, temperature and shear stress have been illustrated graphically in presence of pertinent physical parameters due to wide occurrence of non-Newtonian fluid behaviour in different fields of engineering and technology.
