Hello! In the Ansys Fluent manual, there is an equation for the momentum conservation of a film in the Eulerian film model, which has the following form: (see attachment).

Please help me find some articles or scientific papers that justify this equation, in particular the choice of coefficients for the third and fourth terms on the right-hand side. The manual only states that they are guided by a quadratic velocity profile.
