  Hi friends
  What is reference erosion rate ( oka model) formula in fluent ?
  is it equal to 84.714(Hv)^-0.79 * [(V_p/V')^k_2]*[(D_p/D')^k_3] ?
  I have all the parameters except V-p (impact vlocity) and I don't know how to find it, to put it in the formula.
  I am very confused.

  Hello:
  Reference Erosion Rate is the rate at 90┬║ impact angle. You may wish to look at the paper referenced here.

  The impact velocity is calculated by Fluent - it's how fast the particle is going when it hits the surface!
