Thermal transfer by conduction / radiation

Since 2007, EC2MS firm is developing a branch specialised in the modelling of the thermal behaviour of composite systems. This new orientation brings the problematic of energy saving and more generally of sustainable development to the heart of our preoccupations.

Thus, in partnership with different thermal insulation manufacturers, EC2MS contributes to different projects aiming at developing new insulating materials with high efficiencies (nanometric super-insulating materials), improving the thermal performances of standards thermal insulators (EPS, PVC foams, glass fibers, ...) and finaly improving the methods of characterization of the thermal performances of insulating materials.

The scientific field concentrates on the coupled radiation-conduction heat transfer in semi-transparent materials. Our area of expertise concerns the direct modelling of the conductive or radiative properties of composite materials from their microstructure but also includes the identification of these properties from indirect measurements (FLASH thermograms, hot-wire measurements, spectrometric measurements). Several studies conducted on various materials (particle beds, polymer foams, metallic foams, fibrous materials, nanoporous silicas) or using different measuring methods (FLASH measurements, hot-wire measurements), gave rise to several publications in scientific journals with reviewing committee. At the same time, EC2MS also have some scientific abilities with convective heat transfer phenomenons.

The abilities of the society can be divide in four topics :

1 - Predict the radiation-conduction heat transfer

Solving of the Radiative Transfer Equation (RTE) using the Discrete Ordinates Method (DOM)

Prediction of the radiative properties β_λ, κ_λ, σ_λ, P_λ(θ)

Prediction of the conductive properties k_c : Finite Volume Methods
