Consider a steady, laminar, incompressible and two dimensional boundary layer flow and heat transfer of a viscous nanofluid past a permeable stretching/shrinking sheet coinciding with the . Numerical diffusion is a difficulty with computer simulations of continua (such as fluids) wherein the simulated medium exhibits a higher diffusivity than the true medium. This phenomenon can be particularly egregious when the system should not be diffusive at all, for example an ideal fluid acquiring some spurious viscosity in a numerical model. The work in general copes with non-Newtonian laminar flow using the finite element method, and some basic theory of the subject is included in the opening chapters of the book. -- Springer-Verlag The Least-Squares Finite Element Method: Theory and Applications in Computational Fluid Dynamics and Electromagnetics.

Turbulence modeling means the formulation of the mathematical relationships required to obtain solutions of the averaged equations of motion. Averaging is necessary because the time-dependent Navier-Stokes equation cannot be solved analytically, and the range of scales occurring in turbulence limits the possibility of numerical solution by supercomputer to simple flow geometries and low. (a) Laminar flow occurs in layers without mixing. Notice that viscosity causes drag between layers as well as with the fixed surface. (b) An obstruction in the vessel produces turbulence. Turbulent flow mixes the fluid. There is more interaction, greater heating, and more resistance than in laminar flow. If the flow is laminar, a result similar to that for circular tubes is available for the friction factor, which can be written as. f C= / Re, where. C. is a constant that depends on the aspect ratio. ab /, and the Reynolds number is defined using the equivalent diameter. values of the A few constant. C. The current development of micro-scale technologies increases the interest in viscous flows with low and moderate Reynolds numbers. This work theoretically studies the entrainment flow of a viscous jet emerging from a plane wall into a half-space with the objective to understand the conditions where a similarity model can approximate a realistic flow.
