WebK-epsilon (k-ε) turbulence model is the most common model used in computational fluid dynamics (CFD) to simulate mean flow characteristics for turbulent flow conditions. It is a two equation model that gives a general description of turbulence by means of two transport equations ( partial differential equations , PDEs). The correlation should, however, be treated with caution. For instance, dichloromethane has a value of ε r of 9.08 (20 °C) and is rather poorly soluble in water (13 g/L or 9.8 mL/L at 20 °C); at the same time, tetrahydrofuran has its ε r = 7.52 at 22 °C, but it is completely miscible with water See more The relative permittivity (in older texts, dielectric constant) is the permittivity of a material expressed as a ratio with the electric permittivity of a vacuum. A dielectric is an insulating material, and the dielectric constant … See more Relative permittivity is typically denoted as εr(ω) (sometimes κ, lowercase kappa) and is defined as where ε(ω) is the See more Energy The relative permittivity is an essential piece of information when designing capacitors, … See more Permittivity is typically associated with dielectric materials, however metals are described as having an effective permittivity, with real relative permittivity equal to one.
