flow over a circular cone has a many real applications. i want to analyse it for mass conservation. I have few doubts .
1. co ordinate system: either cylindrical or spherical
2. co ordinate system for cone is orthogonal or non orthogonal

if it is non orthogonal then there is a huge change in governing equation itself. any one can suggest References for it......... or governing equation for flow over a circular cone (mass conservation)
