Three dimensional CuO–Water nanofluid flow considering Brownian motion in presence of radiation

摘要

In this investigation, three dimensional CuO–Water nanofluid flow between two horizontal parallel plates through porous medium in a rotating system is scrutinized. Micro mixing in suspensions is taken into account while calculating viscosity. The problem under consideration gives rise to set of nonlinear partial differential equations. Using proper change of variables, these give rise to set of ordinary differential equations. This cannot be solved using analytical methods, so Mathematica is employed for obtaining solution using HAM. To avail insight of the physics of the problem, the effects of pertinent parameters are discussed. Nanofluid temperature can be increased by increasing either of Radiation parameter, Magnetic parameter, Rotation parameter, Thermophoretic parameter or Brownian parameter. It is observed that skin friction can be reduced by reducing Reynolds number and rotation parameter. Also it can be established that Nusselt number and Sherwood number can be decreased by increasing values of Thermophoretic parameter, Schmidt number, Brownian parameter or rotation parameter.
