For each statement, choose whether the statement is true or false, and discuss your answer briefly: (a) The physical validity of a CFD solution always improves as the grid is refined. (b) The x-component of the Navier–Stokes equation is an example of a transport equation. (c) For the same number of nodes in a two-dimensional mesh, a structured grid typically has fewer cells than an unstructured triangular grid. (d ) A time-averaged turbulent flow CFD solution is only as good as the turbulence model used in the calculations.
3.) Transport review: For steady-state flow of water in a stationary pipe of radius R, simplify
the Navier-Stokes equation to a simple 2nd order ODE. Assume a pressure drop AP over the
length of the pipe (L). What are two boundary conditions that can be used? Do not solve.
A boundary layer is a thin region (usually along a wall) in which viscous forces are significant and within which the flow is rotational. Consider a boundary layer growing along a thin flat plate. The flow is steady. The boundary layer thickness ? at any downstream distance x is a function of x, free-stream velocity V∞, and fluid properties ? (density) and ? (viscosity). Use the method of repeating variables to generate a dimensionless relationship for ? as a function of the other parameters. Show all your work.
