What are Laminar and Turbulent flows?
In fluid dynamics, laminar flow is characterized by smooth or regular paths of fluid particles, in contrast to turbulent flow, characterized by the irregular movement of particles of the fluid. The fluid flows in parallel layers (with minimal lateral mixing), with no disruption between the layers. Therefore, the laminar flow is also called streamline or viscous flow. The term streamline flow is descriptive of the flow because, in laminar flow, layers of water flow over one another at different speeds with virtually no mixing between layers. Fluid particles move indefinite and observable paths or streamlines. When a fluid is flowing through a closed channel such as a pipe or between two flat plates, either of two types of flow (laminar flow or turbulent flow) may occur depending on the velocity, viscosity of the fluid, and the size of the pipe (or on the Reynolds number). Laminar flow tends to occur at lower velocities and high viscosity.
In fluid dynamics, turbulent flow is characterized by the fluid’s irregular particles (one can say chaotic). In contrast to laminar flow, the fluid does not flow in parallel layers, the lateral mixing is very high, and there is a disruption between the layers. Turbulence is also characterized by recirculation, eddies, and apparent randomness. In turbulent flow, the fluid’s velocity at a point continuously changes in magnitude and direction. Detailed knowledge of the behavior of turbulent flow regimes is important in engineering because most industrial flows are turbulent. Unfortunately, the highly intermittent and irregular character of turbulence complicates all analyses. Turbulence is often the “last unsolved problem in classical mathematical physics.” The primary tool available for their analysis is CFD analysis. CFD is a branch of fluid mechanics that uses numerical analysis and algorithms to solve and analyze problems that involve turbulent fluid flows. It is widely accepted that the Navier–Stokes equations (or simplified Reynolds-averaged Navier–Stokes equations) can exhibit turbulent solutions, and these equations are the basis for essentially all CFD codes.
You can see the projects ‘Smoke Ventilation Using Jet Fan in a Tunnel’ and ‘Boiling Phenomenon and Bubble Formation’ link below, which are carried out by the MR-CFD team:
The fluid in these examples has turbulent treatment, although most of the projects available on www.MR-CFD.com have used laminar or turbulence behavior for the viscous model.
