Analysis of the k-epsilon turbulence model for simulation of compressible flows The k--epsilon turbulence model is widely used to simulate compressible flows. The model has been evaluated extensively in incompressible flows. However, the extension of the model to compressible flows needs more testing...
Numerical analysis was performed on circular free jets through finite difference scheme and k-epsilon turbulence model. In describing the governing partial differential equations, Landau transformation was applied so that the nodal points were appropriately distributed within the significant part of the fiel...
The accuracy of k-蔚 turbulence models for the swirling flow in the Turbine 99 draft tube is the subject of this work. The relation of the first-order upwind, second-order upwind, third-order upwind (QUICK) and Power Law schemes used with these models has been studied. As the turbulent ...
both the standard k-ε model and the Realizable k-ε model of the filter inside flow numerical simulation analysis had higher calculation accuracy,whose result had high degree of agreement with the test results.In order to further optimize the filter structure,the internal flow pattern was ...
Energy dissipation rateThe K–[equation]model used in turbulence simulations involves the transport equations for the turbulent kinetic energy and its dissipation rate. In contrast to the turbulent energy equation derived...doi:10.1007/s00162-019-00490-2Hamba, Fujihiro...

The existence of photonic band gaps for many known 2D photonic crystals is explained through the degeneracy analysis. Some structures with large band gaps are also found through the present degeneracy analysis. 展开 关键词: k-epsilon turbulence model positivity of turbulence variables unstructured grids...
This study presents a mathematical model to evaluate the performance of gas pipelines during hydrogen injection in a gas pipeline-compressor station. The developed model presents the calculation of methane–hydrogen mixture (CH4/H2) transportation throug
The two dimensional, compressible, thin layer Navier-Stokes equations with the Baldwin-Lomax turbulence model and the kinetic energy-energy dissipation (k-epsilon) model are solved numerically to simulate the flow through a cascade. The governing equations are solved for the entire flow domain, witho...
