    Graduate Solving Navier Stoke Problem with 3D Equation and Lubrication Approximation

    Hi every body thanks for the reply Jacqueline u obtain the same as the paper And jack in the doc they assume p doesn't change in r But as You say a c depent in theta What do u think?

    Graduate Solving Navier Stoke Problem with 3D Equation and Lubrication Approximation

    hi every body, I am doing an analysis of a paper about a tool used in oil well drilling, they use 3D navier stoke equation and by lubrication aproximation the get this -(1/r) ∂p/∂θ + k (∂( 1/r ∂(rw)/∂r )/∂r )=0 its necesary to get w so i use integral but i obtain an irreal i used...
