This indicated that in the larger pore sizes the flow will be mainly viscous flow, which is usually modeled using Darcy's law, while in the extremely small pore sizes the dominating flow regime is Knudsen diffusion, which can be modeled using Knudsen's Diffusion law or in cases where ...
The Spalart-Allmaras turbulence model is a RANS approach that involves a single governing kinematic equation to describe viscous eddy current flow. The model was specifically derived for use in aerodynamic applications involving wall-bounded systems as well as in turbomachinery applications. The model in...
solves the viscous Burgers equation either by using the original heat equation (2) and the identity , or else by using the equations of motion (3). This relation between the Burgers equation and the heat equation is known as the Cole-Hopf transformation. The paper of Csordas, Smith, and...

ability to stay aloft as well as the power and fuel needed to keep it there. Lift induced (or just induced) drag occurs as the result of the creation of lift on a three-dimensional lifting body (wing or fuselage). It has two primary components: vortex drag and lift-induced viscous ...
It is further possible to solve aThermoacoustic-Solid Interactionproblem, which solves a linearized frequency-domain version of theNavier-Stokes equationsand can consider losses in the explicitly modeled thermal and viscous boundary layers. Although this is more computationally expensive than an acoustic-...
(more curvature upwards then curvature downwards). We can create a similar asymmetry in the flow with a stationary cylinder by placing a small sharp-edged flap at the rear edge and positioned slightly downwards. Real viscous flow might not necessarily flow as smoothly around the little flap as ...
