thermal mathematical model (TMM)


numerical representation of an item and its surroundings represented by concentrated thermal capacitance nodes or elements, coupled by a network made of thermal conductors (radiative, conductive and convective)


  • NOTE 1 For thermo - hydraulic modelling enthalpy and fluidic conductors are used in addition.
  • NOTE 2 A TMM generates for all nodes / elements a temperature history, an energy balance in addition pressure drops and mass flow rates for thermo - hydraulic modelling.
  • NOTE 3 Numerical representation can be performed by lumped parameter, finite difference or finite element methods.
