Mechanical and fluid simulation
The most important needs of manufacturing companies is new products design and to update and improve old products.
Today, there is a possibility that all stages of modeling software to design with speed and good quality and done by the software.Today, it is possible that all design stages with the help of software modeling with appropriate speed and quality.During the design process can be carried out with help of finite element analysis software,all required analyzes including : static analysis, dynamics, heat transfer fluids (CFD), and mechanism analysis and can be realized in other analyzes on the model and series and improved the strengths and weaknesses of the plan.also, the new rendering tools can provide proper images and full specifications of the product asking them to be used as industrial image. (CFD).
Araco has a history of industrial activity and proper recognition of the mechanisms and methods of production is ready to carry out an analysis of the mechanical, fluids (CFD) and aerodynamics in the various spheres of industry, in the shortest possible time and with the best quality. (CFD) .

  • Analysis and simulation of fluid and heat transfer
  • Static and dynamic analysis and simulation
  • Analysis and simulation of aerodynamics
  • PyroSim and FDS Fire Simulation

CFD - Computational Fluid Dynamics - CFD
In continuum mechanics, fluid mechanics to form one large branch. Fluid mechanics begins with the same principles of solid mechanics , but what distinguishes them from one another, this is a fluid unlike solids are not able to withstand shear stress. Knowing this, it is planned equations for fluid motion analysis. this equations to respect both the British and the French mathematician called Navier-Stokes equations. CFD - Computational Fluid Dynamics - in fact is solve the Navier-Stokes equation for the small size of the original model. In this way the total desired volume is divided into very small volumes in operation meshing and after applying the boundary conditions, the equation is solved for all elements.
Computational Fluid Dynamics- CFD-  in terms of the overall trend is similar with static and dynamic FEM analysis . both methods are used to solve a much smaller element than the original model.
Today , with increasing computer processing speeds,CFD and FEM analyzes have found a special place in the design and failure analysis. Important things that can be calculated in Computational Fluid Dynamics :
  • Plot speed, temperature and fluid pressure in any point of the model
  • Plots and counter the speed, temperature and fluid pressure in the interior and exterior surfaces
  • Diagram of the fluid flow path
  • heat transfer charts and plots in the outer surfaces and boundary
  • Calculation of speed, temperature and pressure at different levels and volumes
  • Diagram of the flow path
Analysis and simulation of heat transfer and fluid that can be done with software such as: Fluent, Ansys and Flow works used in different parts of the industry, some of these include:
  • Analysis and simulation of industrial ventilation and air conditioning
  • Analysis and simulation of turbine and compressor
  • Analysis and simulation of tunnel ventilation
  • Analysis and simulation of heat exchanger
  • Analysis and simulation of chimneys
  • Analysis and simulation of pumps
 

 
Static and dynamic analysis and simulation - finite element method - FEM - FEA
Finite Element Method is a numerical method to approximate solutions of partial differential equations and solving integral equations. The practical application of finite element commonly referred to as finite element analysis (FEA). Under this method the complete elimination of differential equations or simplify them ordinary differential equations which are solved by numerical methods such as Euler. in fact,in the finite element method the object or collection divided into very small elements and solved the equations for each component. It should be noted, that the accuracy of finite element analysis strongly depends on the quality of modeling, taking into account boundary conditions and allocation of the correct material and proper meshing of the model.  Simulation and analysis of finite element is used for static and dynamic loading of mechanical equipment and structures.
