Determination of K

Case Study I: Planar Geometry Sudden Contraction, Hentrance:Hexit = 3:1, Re=0.001, _=1.

• From simulation, _ptotal = Ktotal= 55.5;

• Using simplified Eq. of Motion:

_ptube= Ktube= 48+1.78=49.78;

• _pcontraction= Kcontraction=55.5-49.78=5.72;

• Since _=1, U1= 0.5[1-(y2/1.52)], _

_p=1.78

_p=48
