Finite element analysis for thermal applications

Finite element simulation is required for problems in the widest variety of domains in the thermal field.  This covers modeling of heat transfer by conduction, convection (free of forced) and radiation in an infinite medium or in a cavity.

D2S offers services that cover the whole project from start to finish :

• Measurements: (see Monitoring) 
  • Temperature (thermocouples, PT100)
  • Infrared measurements
  •  …
• Numerical Simulations:
  • Generation of digital model based on FEM (nodes, elements) for 2D, 3D and axis-symmetric simulations
  • Affectation of physical properties like thermal conduction coefficient, density and specific heat  (all temperature dependent)...
  • Boundary conditions : prescribed temperature, heat flux density, wall temperature dependent heat exchange coefficient, thermal emission coefficient of sidewalls in case of radiation ...
  • Loadings : imposed temperature, internal heat source,...
  • Steady state analysis
  • Transient thermal linear and non-linear analysis (thermal shocks,...) 
  • Thermo-mechanic analysis
  • Thermal contact medium
  • Regulation-adjustment medium
  • Calculation of temperature distribution, heat flux, thermal stress and strains, etc…
  • Post-processing : visualization ...
• Application domain:
  These kinds of simulations often concern the energy sector (nuclear industry).  Thermal analysis is also used for problems in the widest variety of domains, ranging from the design of an oven or heat exchanger, to analysis of effects induced by heat treatment or the study of solidification of a cast part.
