The general transport equation is \(\frac{\partial(\rho \Phi)}{\partia

1.	The general transport equation is \(\frac{\partial(\rho \Phi)}{\partial t}+div(\rho \Phi \vec{u})+div(\Gamma grad \Phi)+S\). For Eulerian equations, which of the variables in the equation becomes zero?(a) Γ(b) ρ(c) Φ(d) \(\vec{u}\)This question was addressed to me in an interview.I want to ask this question from Euler Equation in division Governing Equations of Fluid Dynamics of Computational Fluid Dynamics
Answer» Correct CHOICE is (a) Γ Explanation: Γ is the diffusion COEFFICIENT in the GENERAL TRANSPORT equation. Diffusion of any PROPERTY is not included in Eulerian equations. So, Γ=0.
