1. unidirectional assumption where vy=vx=0
laminar flow
2. 1D flow assumption where dvx/dz=0, dvx/dx=0
3. newtonian flow shear stress = mu (du/dy), mu is constant
4. no pressure gra- assumption where P=0, dp=0
dient
5. shear thinning aka psuedoplastic, like blood (gets this profile from RBCs). exponential decrease
graph, power law fluids, Tau=(mu)*(du/dy)^n
6. shear thickening a dilatant like cornstarch and water, exponential increase graph, power law fluids,
Tau=(mu)*(du/dy)^n
7. casson flow flow profile, applies to lubricants, sqrt(tau) = sqrt(tauy) + sqrt(mu*du/dy)
8. bingham flow flow profile, applies to mud and toothpaste, tau=tauy

9. incompressible assumption where rho (density) is constant, fluid element lengthening in one di-
rection must be thinning proportionally in the other direction to conserve volume
one of the assumptions for euler's equation, ideal fluid and Bernoulli equation
10. steady flow flow does not depend on time, any derivative including time goes to zero, a =
(v*gradient)v.
one of the assumptions for Bernoulli
11. fully developed assumption where velocity magnitude is constant (v=constant, dv/dx = 0) (not
flow dependent on x location)
12. ideal fluid type of fluid that experiences only inviscid and incompressible flow, the fluid we
use when applying Euler's equation, constant along streamline
2 of the assumptions for Bernoulli
13. inviscid neglect viscosity (small viscosity compared to large velocity). only surface forces are
due to pressure.
one of the assumptions for Bernoulli
14. 5 classes of rela- -kinematics
tionships -stresses and tractions
-balance relations
-constitutive relations
-initial/boundary conditions
15. kinematics one of the 5 classes of relationships, used to compute velocities, accelerations,
shear rates etc.
16. stresses and trac- one of the 5 classes of relationships, used to quantify intensity of forces acting on
tions oriented area
17. balance relations one of the 5 classes of relationships, used to ensure balance of mass, momentum,
energy
