Fluid flow momentum equation
WebThe Navier-Stokes equations make combined statements that a flowing fluid must obey conservation of momentum as it undergoes motion and that mass is conserved during … WebA momentum-forcing term is added to the Navier–Stokes equation in order to impose the no-slip boundary condition on the wavy wall. Parametric study is carried out to analyze the fluid flow characteristics by varying wave geometry factor (WG Factor) of crest–crest (CC Model) wavy wall configurations for Reynolds number ranging from 10 to 50.
