| Abstract | A mathematical model of convective steady flow over rotating disks in an orthotropic porous medium has been developedand solved the non-dimentional governing equations for flow by the shooting method that uses fourth order Runge- Kuttaintegration technique and Newton's method. Magnitude of radial velocity of fluid decreases near the surfaces of the disks forincreasing value of Reynolds number. Impact of stretching parameters on the radial and tangential velocity profiles is observed.Computational results are presented graphically for various cases of parameters on velocity (radialf ?and tangentialg) andtemperature profiles and table values are reported for skin friction and Nusselt number along both disks. It is observed that as theReynolds number increases, the tangential velocity decreases. As we move far away from the disk the effects of physical parametersis not significant. It is seen that when the stretching parameter increases the radial velocity increases initially and when ??=0.3onwards the radial velocity decreases. This type of study finds application in industrial and engineering fields such as turbineengines and electronic power generating systems etc. |
