Heat Transfer Problem Solving

Thermal analysis  allows the evaluation of the temperature behavior of products under the action of heat (convective flow, radiation, heat conduction). Thermal analysis can be used independently to calculate the temperature and thermal fields in the structure. Thermal calculation together with static analysis is used to estimate thermal strains arising in the product.

Thermal analysis includes:

  • analysis of steady-state and transien heat transfer
  • spectral analysis
  • conductive, convective, radiative heat transfer
  • heat of phase transitions
  • mass transport
  • temperature dependent material properties

Steady-state formulation of the problem associated with calculation of the steady-state (stationary) temperature fields of structures under the applied thermal boundary conditions.

Transient formulation of the problem associated with calculation of transients of units. Calculation of temperature fields is carried out according to the time when thermal loads were applied relatively recently, and the system is an active redistribution of temperature fields. All the properties of the materials used in the calculation (thermal conductivity, specific heat, density, enthalpy) can be nonlinear.

The boundary conditions are used terms: temperature, heat flux, convective heat transfer, thermal power, radiation.
