BOUNDARY LAYER THEORY
LECTURE-03
CONTENTS:-
 Momentum Integral Equation (Von Karman Momentum Integral
Equation)
PROF. SANJEEV GUPTA
Von Karman Momentum Integral Equation
According to the continuity equation for a steady incompressible fluid flow
Mass rate of flow entering AD + Mass rate of flow entering DC
= Mass Rate of flow leaving BC
Mass rate of flow entering DC
= Mass Rate of flow leaving BC - Mass rate of flow entering AD
Or
Boundary layer theory 3
Now let us calculate momentum flux through CV
Rate of change of momentum of the CV = Momentum flux through BC - Momentum
flux through AD - Momentum flux through DC
