OpenFOAM for computational hydrodynamics using finite volume method

Partial differential equations may explain anything from planetary movement to tectonic plate, yet it is notoriously difficult to resolve them. Turbulence is present in nearly all fluid flows, and pure laminar flow is extremely unusual in practice. The Large Eddy Simulation (LES) computational model is employed for the simulation of turbulence flow on a spillway having four inlets with a single outlet. Such flows are observed at hydroelectric power dams all over the world. The fluctuated flows produced a large amount of energy in terms of electricity that costs a very low amount compared to the energy obtained in tidal power sectors. In the production of hydropower energy, the flow simulation is of great interest. This paper focuses on the study of turbulence kinetic energy with the help of a LES model. The spillway considered in this paper contains four inlets and a single outlet. The four inlets will allow more flow which will insert more pressure nearer the outlet. The kinetic energy is computed at the inlets and outlet in the turbulent flow. The fluctuated velocity along with the mean velocity at the inlets and outlet is also computed along with the pressure. The C++-based programming is made, which is simulated in Open-source Field Operation and Manipulation (OpenFOAM). The graphs are presented for a better understanding of readers.

Automated summary

This paper utilizes a Large Eddy Simulation (LES) computational model to study turbulence flow on a spillway with four inlets and a single outlet. By calculating parameters such as kinetic energy, fluctuated velocity, mean velocity, and pressure, the turbulent flow is analyzed.
