Scaling group transformation for MHD boundary-layer flow of a nanofluid past a vertical stretching surface in the presence of suction/injection

摘要

The problem of laminar fluid flow which results from the stretching of a vertucal surface with variablestream conditions in a nanofluid has been investigated numerically. The model used for the nanofluid incorporates the effects of Brownian motion and the mopharesis in the presence of magnetic field. The symmetry groups admitted by the corresponding boundary value problem are obtained by using special form of tie group transformations viz. scaling group of transformation. An exact solution is obtained fortranslation symmetry and numerical ralutiom for scaling symmetry. This solution depends on a Lewisnumber, magnetic field. Brownian motion parameter and thermopharetic parameter The conclusion isdrawn that the flow held and temperature and nanoparticle volume fraction profiles are significantlyinfluenced by there parameters.
