Heat flux measurement to validate CFD thermal simulations

Use heat flux sensors

Did you know that heat flux can be measured? The FHF series heat flux sensors is used to verify simulated heat flux.

Heat transfer and thermal management of designs, devices and processes are often optimised using CFD simulation. The results are estimated temperatures and heat fluxes. Until now, only measurement of temperature is very common for validation purposes.

The Hukseflux FHF series heat flux sensors offers the first really practical solution to add heat flux to you measurements. For example: they can serve to measure heat flux boundary conditions as input for your thermal simulation (e.g. Ansys, COMSOL, OpenFoam, SimScale, Abaqus, etc.) or they can be used as validation of calculations.

How heat flux sensors work

 

Heat flux sensors measure a temperature difference across a thin layer of material. They typically employ a thermopile, which is manufactured by creating an alternating pattern of two dissimilar conductors, generally metal alloys. The output is a millivolt signal proportional to the local heat flux.
