Development of Three-point MEMS heat flux sensor on sub-millimeter scale


A three-point heat flux sensor for internal combustion engines has been developed with MEMS (Micro-Electro-Mechanical Systems) technology. This sensor can measure wall heat fluxes at adjacent three points for detecting turbulent properties. One of the strong point is a high S/N ratio enough to observe the instantaneous heat transfer in the engines by using RTD (Resistance Temperature Detector) method.

We have developed a heat flux sensor which can detect local heat flux distribution. It is expected that the sensor contributes to elucidation of the engine wall heat transfer characteristics and turbulent properties in the combustion field.
