Flow Features

The present literature illustrates the radiative couple stress fluid runs over a permeable stretched cylinder. The problem has been modelled mathematically introducing the mixed convective condition and magnetic effect. Additionally, the analysis of entropy generation provides the fine points of the flow. The leading PDE equations of the system have been framed non-dimensionally using proper transformation. The resulting ODEs are tackled using by Spectral quasi-linearization method (SQLM). A convergence schematic was obtained graphically. Consequence of various parameters on the flow features has been delivered via graphs and tables. Result signifies that Bejan number declines due to magnetic source. The entropy generation escalates for magnetic parameter, Reynolds number, but couple stress factor discloses the dual effect. The couple stress parameter allows Nusselt number to reduce at the rate 19.05%, whereas heat transport enhances for radiation at the rate 1.67%. Skin friction enhances for couple stress factor at the rate 8.45%.

The Impact

AbstractAn attempt has been made to examine the effects of magnetohydrodynamic couple stress fluid in peristaltic flow with porous medium under the impact of slip, heat transfer and wall properties. The expressions are obtained for temperature, coefficient of heat transfer and velocity. Influences of different parameters, the Hartmann number, Brinkman number and adaptability parameters on the temperature and warmth trade coefficient are discussed through outlines.
