Description Project Description of Internal Flow with Different Flow Regimes. The present problem simulates the internal flow of water through a simple horizontal pipe, which due to the symmetrical structure of this pipe, half of its geometry consists of a semi-cylinder has been studied by ANSYSFluent.The purpose of the present simulation is to study and compare fluid flow in different flow. Turbulent flows are significantly affected by the presence of walls. The k-epsilon turbulence model is primarily valid away from walls and special treatment is required to make it valid near walls. The near-wall model is sensitive to the grid resolution, which is assessed in the wall unit y+ (defined in section 10.9.1 of the Fluent user manual).
For no-slip wall conditions, ANSYSFLUENT uses the properties of the flow adjacent to the wall/fluid boundary to predict the shear stress on the fluid at the wall. In laminar flows this calculation simply depends on the velocity gradient at the wall, while in turbulentflows one of the approaches described in this section in the separate Theory.

I am trying to simulate 2D laminar developing flow and heat transfer in grooved enhanced pipe. The details are . Diameter 40mm, Length of pipe 400mm . Inlet velocity 0.0125375m/s. pressure outlet. heat flux 50w/m^2 . Results. When I calculate Nusselt number in this way. The v2-f turbulence model describes the anisotropy of the turbulence intensity in the turbulent boundary layer using two new equations, in addition to the two equations for turbulence kinetic energy (k) and dissipation rate (ε). The first equation describes the transport of turbulent velocity fluctuations normal to the streamlines.
Most fluid flows (gas or liquid) are turbulent in nature.These flows are characterized by unsteady and irregular fluctuations of transport quantities such as mass, momentum and species in both space and time. These fluctuations enhance flow mixing. Examples of these flows are widespread — from ocean waves and cyclones to airflow over an automobile, from Continue.
Jun 18, 2022 · The unsteady RANS governing equations, integrating the turbulence and ADM model, are applied in the numerical calculation performed by the CFD software ANSYS Fluent 2020 R2. The coupled method is employed for the pressure-velocity coupling because of its implicit nature, being that it is more stable than the segregated solver and it will.
Hello Ansys Community, I am solving a two-phase flow problem using DPM(Discrete Phase Model) in ANSYSFluent. The two-phases are lubricating oil and air. The problem is that I need to input whether it is laminar or turbulent. In order to do that, I need to find the Reynolds number.

Fluent offers the option to enhance near-wall modeling integrated into the turbulence Κ-ε model . Near the alloy surface, the fidelity of numerical solutions is extremely important to predict accurately pressure and temperature gradients as the core turbulence flow transforms into boundary layers closer to the wall.
