Introduction to CFD and Important CFD Projects

In this article we are going to study about CFD and CFD projects, which you can do in your academic career.

Computational fluid dynamics (CFD) is a branch of fluid mechanics that uses numerical analysis and data structures to solve and analyze problems that involve fluid flows. Computers are used to perform the calculations required to simulate the interaction; of liquids and gases with surfaces defined by boundary conditions. With high-speed supercomputers, better solutions can be achieved. Ongoing research yields software that improves the accuracy and speed of complex simulation scenarios such as transonic or turbulent flows. Initial experimental validation of such software is performed using a wind tunnel; with the final validation coming in full-scale testing, e.g. flight tests.

Computational fluid dynamics (CFD) is the use of applied mathematics, physics and computational software to visualize how a gas or liquid flows — as well as how the gas or liquid affects objects as it flows past. Computational fluid dynamics is based on the Navier-Stokes equations. These equations describe how the velocity, pressure, temperature, and density of a moving fluid are related.

Simply by changing variables, the administrator can visualize how cold air will flow through the data center under a number of different circumstances. This knowledge can help the administrator optimize the efficiency of an existing cooling infrastructure and predict the effectiveness of a particular layout of IT equipment. For example, if an administrator wanted to take one rack of hard drive storage and split the hard drives over two racks, a CFD program could simulate the change and help the administrator understand what adjustments would be need to be made to deal with the additional heat load before any time or money has been spent.

History of Computational Fluid Dynamics

From antiquity to present, humankind has been eager to discover phenomena based on fluid flow. So, how old is CFD? Experimental studies in the field of computational fluid dynamics have one big disadvantage: if they need to be accurate, they consume a significant amount of time and money. Consequently, scientists and engineers wanted to generate a method that enabled them to pair a mathematical model and a numerical method with a computer for faster examination.

The brief story of Computational Fluid Dynamics can be seen below:

  • Until 1910: Improvements on mathematical models and numerical methods.
  • 1910 – 1940: Integration of models and methods to generate numerical solutions based on hand calculations11.
  • 1940 – 1950: Transition to computer-based calculations with early computers (ENIAC). Solution for flow around cylinder by Kawaguti with a mechanical desk calculator in 1953.
  • 1950 – 1960: Initial study using computers to model fluid flow based on the Navier-Stokes equations by Los Alamos National Lab, US. Evaluation of vorticity – stream function method. First implementation for 2D, transient, incompressible flow in the world.
  • 1960 – 1970: First scientific paper “Calculation of potential flow about arbitrary bodies” was published about computational analysis of 3D bodies by Hess and Smith in 1967. Generation of commercial codes. Contribution of various methods such k-ε turbulence model, Arbitrary Lagrangian-Eulerian, SIMPLE algorithm which are all still broadly used
  • 1970 – 1980: Codes generated by Boeing, NASA and some have unveiled and started to use several yields such as submarines, surface ships, automobiles, helicopters and aircrafts.
  • 1980 – 1990: Improvement of accurate solutions of transonic flows in three-dimensional case by Jameson et. al. Commercial codes have started to implement through both academia and industry7.
  • 1990 – Present: Thorough developments in Informatics: worldwide usage of CFD virtually in every sector.

The bigger picture

The central mathematical description for all theoretical fluid dynamics models is given by the Navier-Stokes equations,; which describe the motion of viscous fluid domains. The history of their discoveries is quite interesting. At first, Claude-Louis Navier conducted studies on a partial section of equations up until 1822. Later, Sir George Gabriel Stokes adjusted and finalized the equations in 1845.
