LBM in fluid dynamics is another concept which means Lattice Boltzmann Method for fluid flows which is nothing but a parallel and efficient algorithm to simulate single and multi phase fluid flows types and incorporates additional physical complexities.

Basically Lattice Boltzmann Method for fluid flows is used in modeling complicated boundary conditions and multiphase interfaces. Some extensions include simulations of fluid turbulence, suspension flows and reaction diffusion. Fluid flow in pipes has 2 primary flow patterns includes parallel travelling and random motion with a critical zone when the flow can be either of these two having one is turbulent and other one is laminar or mixture.

Osborne Reynolds proved that the nature of flow depends on the mean flow velocity of flow in generic flow of direction and on Mean flow velocity (v), the pipe diameter (D) and the density (rho) and the fluid viscosity (mu). By the way a dimensionless variable known to be as Reynolds number which is simply a ratio of the fluid dynamics forces and fluid viscous forces used in fluid flow in pipes.A new concept is working nowadays and that is compressible fluid flow includes a PIPE-FLO compressible simulation which operated including steam and gases under a variety of expected operating conditions.

The main features that it is an easy to understand how piping schematic drawing is working and a robust calculation engine is there. It is quite good accessible to electronic documents used to design various systems.Collaboration tools that provide team with clear view of compressible fluid flow of total piping system. Understanding is very important for a robust design process as man difference is the incompressible fluid like water and compressible fluid and vapors that is the greater change in pressure and density. As in this process pressure, density, enthalpy decrease and velocity, entropy increases.

A Fluid S Resistance to Flow is called VISCOSITY which is very familiar term in fluid dynamics and defined as the quantity that shows a fluid’s resistance to flow that resist the relative motion of immersed objects and it is represented as eta as the ratio of the shearing stress i.e. force/ area to the velocity gradient in a fluid. Newton’s equation also states that resulting shear of a fluid is directly related to the force applied and inversely related to its viscosity. By using f="ma" as Laws of Motion used two terms kinematic, dynamic, absolute or simple viscosity.
