Computational Fluid Dynamics (CFD Analysis)
Computational fluid dynamics, usually abbreviated as CFD, is a branch of fluid mechanics that uses numerical methods and algorithms to solve and analyze problems that involve fluid flows and temperature distribution effects.
There are various methods and approaches to do a CFD analysis. In all of these approaches the basic procedure that is followed is shown below.
  • The geometry (physical bounds) of the problem is defined.
  • The volume occupied by the fluid is divided into discrete cells (the mesh). The mesh may be uniform or non uniform.
  • The physical modeling is defined – for example, the equations of motions + enthalpy + radiation + species conservation
  • Boundary conditions are defined. This involves specifying the fluid behavior and properties at the boundaries of the problem. For transient problems, the initial conditions are also defined.
  • The simulation is started and the equations are solved iterative as a steady-state or transient.
  • Finally a post processor is used for the analysis and visualization of the resulting solution.
Trans heat can take up jobs with requirement of CFD analysis to ensure correct performance predictions and correct serious issues in the design stage itself.
