Heat Flux Sensing Solutions: A short review



This short review about Heat Flux Sensing Solutions aims to give the reader a broad overview of all the research and industrial existings solutions to perform heat flux measurements.


Brief Introduction to heat flux sensing solutions



heat flux

Heat Flux is the rate of heat energy that passes through a surface. Depending on its exact definition, its unit can be expressed as either W/m2 or W. Temperature gradient in a given environment results in the creation of a heat that flows from the hot to the cold side of the given system. The thermal transfer coefficient of the given system is also important. Heat flux can be estimated with two different methods:

  • Directly with Heat Flux Sensors
  • Indirectly using Temperature Sensors.

A Heat Flux Sensor is a Seebeck sensor: When heat passes through the sensor, the sensor generates a voltage signal. This voltage signal is proportional to the heat passing through the sensor. Thus, they can be used for many industrial or research applications implying a temperature gradient throughout a surface.
