For moderately large Reynolds numbers, this simple approach can provide very high accuracy while using a small number of grid points. In the case where the Reynolds number105, the exact solution is not available and a discrepancy exists in the literature. Our results clarify the behavior of the...
The Reynolds number is defined as the ratio of inertial forces to viscous forces and consequently quantifies the relative importance of these two types of forces for given flow conditions. Reynolds numbers frequently arise when performing scaling of fluid dynamics problems, and as such can be used...
For clarity we can expand the exponents for each dimension into simultaneous equations: {eq}\text{L}: -3 + 1 + 1 -(1 - 2) = 0 {/eq} {eq}\text{M}: 1 - 1 = 0 {/eq} {eq}\text{T}: -1 -(-2 + 1) = 0 {/eq} So the Reynolds number is dimensionless: {eq}[Re...
The open source software OpenFOAM is used for the flow calculations. It is shown that the new model increases the accuracy of flow simulations compared to the commonly used Spalart-Allmaras (SA) and Shear-Stress-Transport (SST) k-ω models for several of these flows. 展开 ...

Calculation of complex near‐wall turbulent flows with a low‐Reynolds‐number k‐ϵ model An improved low-Reynolds-number k - model has been formulated and tested against a range of DNS (direct numerical simulation) and experimental data for cha... P Koutmos,NC Kostouros - 《International...
This correction is normally implemented, for example, in the DLM. As it is based on the linearised velocity potential equation, the Prandtl–Glauert correction is restricted to thin wings and small angles. Theoretically, a flow can be regarded as inviscid if the Reynolds number is large enough...
An equation is a mathematical statement saying that two amounts or values are the same, for example 6x4=12x2. 2.(多种因素需加以综合考虑的)平衡,综合体 An equation is a situation in which two or more parts have to be considered together so that the whole situation can be understood or...
