ISO 10211:2007, thermal bridges in building construction
QuickField validation of the test case A.4 presented in ISO 10211:2007 Thermal bridges in building construction.
3D problem of heat transfer.
Thermal conductivity of insulation λ1 = 0.1 W/K-m.
Thermal conductivity of metal λ2 = 50 W/K-m.
The metal bar penetrates the insulation wall. Determine the flux and the thermal coupling coefficients.
Air contact surface thermal resistance Rs is caused by the convection. The convection coefficient value is reciprocal to the surface resistance value:
α = 1 / Rs [W/(K·m²)].
Temperature distribution in media:
|Heat flux||0.543 W||0.54 W||1%|
To comply with the ISO 10211:2007 the difference between calculated and reference heat flux should be less than 1% (0.005°C - for temperature). This simulation accuracy complies with the requirements of ISO 10211:2007.
