Hi I'm a post graduate student.. Can U pl tell me how can i implement the derivative boundary conditions.. for example the partial derivative of x-velocity along x-direction is equal to zero, or the partial derivative of pressure in any direction is zero...
thank you for ur reply |

Hi
What do you mean by "implement"? Fluent will take care of the tangentional velocity magnitudes near the wall by the no-slip condition, and for fully developed flows, the derivative of the x-velocity in the x direction is zero, so you don't have to implement anything. Sorry if I misunderstood your question! Regards |

Hi I'm a post graduate student.. Can U pl tell me how can i impose a boundary condition, second derivative of velocity(U) w.r.t x equal to zero.... How can I apply a linearly varying temperature along a wall..
