Heat Flux

Definition - What does Heat Flux mean?

Heat flux is the thermal energy transferred from one substance to another per unit time and area denoted by temperature change measured in watts per meter squared units. In simple terms, it is the heat transferred per unit area. To obtain this value, one must obtain the change in temperature, the thermal conductivity of the medium of conduction and the direction of the heat transfer. Accurate figures are obtained when the system is in a steady state condition.

This knowledge helps in determining heat transfer fluids, which in turn determines the type of inhibitors and environment variables to be used and controlled to prevent corrosion.

Corrosionpedia explains Heat Flux

Heat flux is a thermodynamic term used in conjunction with various heat transfer analyses so as to develop various energy solutions. As heat transfer is applied in refrigerators, the fluids must be accompanied by corrosion inhibitors since the condition around the closed structures stimulate internal corrosion in the metallic tubes. In corrosion, a higher heat flux indicates that the transferred fluid will increase in temperature and thus contribute to corrosion when oxygen and moisture are part of the system; the velocity of the fluid also determines the level of corrosion.

By the use of heat flux sensors, one can determine crucial information in relation to thermodynamics. Eventually, the raw data collection of various heat flux of materials is used in developing modern sensors which are used in the engineering industry. Materials with high heat flux conduct heat easily.
