Basics Flashcards
What is the material derivative, in both vector & index notation?
What is the velocity gradient tensor?
What is the general decompostion of the motion of a fluid particle in the vicinity of a given point?
What are the rate of strain & rate of rotation tensors?
How does the rigid body of rotation tensor act (and look like)?
How do we define strain?
What does shearing, and the shearing rate, look like?
How is mass flux defined?
What are the integral forms of the compressable & incompressable continuity equations?
How is traction on a fluid particle defined?
How is traction and stress on a fluid particle defined?
Traction affects the surface, stress the interior. When they meet they’re equivalent.
How is the Stress tensor derived?
How does the stress tensor act on a fluid particle?
What do the stress and stress tensors appear as for hydrostatic pressure?
What do the stress and stress-tensor appear as for pure sheer stress?
What is Cauchy’s equation?
What is the stress tensor for a Newtonian fluid?
What does the rotation tensor acting on a fluid particle look like?
