Energy Transfer LP is an American company engaged in the pipeline transportation, storage, and terminaling for natural gas, crude oil, NGLs, refined products and liquid natural gas. It is organized under Delaware state laws and headquartered in Dallas, Texas .
Turbulence kinetic energy is then transferred down the turbulence energy cascade, and is dissipated by viscous forces at the Kolmogorov scale. This process of production, transport and dissipation can be expressed as: D k D t + ∇ ⋅ T ′ = P − ε , {\displaystyle {\frac {Dk}{Dt}}+\nabla \cdot T'=P-\varepsilon ,} where: [ 1 ]
The model attempts to predict turbulence by two partial differential equations for two variables, k and ω, with the first variable being the turbulence kinetic energy (k) while the second (ω) is the specific rate of dissipation (of the turbulence kinetic energy k into internal thermal energy). SST (Menter’s Shear Stress Transport)
Gamma-Re (γ-Re) transition model is a two equation model used in Computational Fluid Dynamics (CFD) to modify turbulent transport equations to simulate laminar, laminar-to-turbulent and turbulence states in a fluid flow. The Gamma-Re model does not intend to model the physics of the problem but attempts to fit a wide range of experiments and ...
There is much discussion on this page as to what Reynolds Transport Theorem actually is. The disagreement being what velocity should appear in the surface integral; whether v {\displaystyle \mathbf {v} } , v r {\displaystyle \mathbf {v} _{r}} or v b {\displaystyle \mathbf {v} _{b}} or a linear combination of these.

In the context of the thermal fluids, the thermal Péclet number is equivalent to the product of the Reynolds number and the Prandtl number (Re × Pr). The Péclet number is defined as: Plan view: For P e L → 0 {\displaystyle Pe_{L}\rightarrow 0} , advection is negligible, and diffusion dominates mass transport.
