Nearly Incompressible Laminar Flow – Equations and Solution Technique Author: John M. Cimbala, Penn State University Latest revision: 31 October 2007 Assumptions and Approximations The fluid is Newtonian with constant properties ( μ , ν , k , α , κ , C P ). The flow is laminar rather than transitional or turbulent. The fluid is nearly incompressible – either an incompressible liquid or an ideal gas at very low Mach numbers . Differential Equations of Motion for Nearly Incompressible Flow (general review) Conservation of mass : 0 i i u x = . Momentum equation : 2 ii i i ji j ij j Du u u u p ρρ u ρ g μ Dt t x x x x ⎛⎞ ∂∂ =+ = + + ⎜⎟ ⎝⎠ .
