Dekusha L. Devices for heat flux measurement based on thermoelectric heat flux transducers

The thesis is devoted to important scientific and technical problem of increasing the accuracy of heat flux measurement, researching and development of new sensors with improved metrological and operating characteristics, creating the basis for a new generation of thermal devices and improves the system of metrological support of heat flux measurement in Ukraine. Methodical errors of measurement of the heat flow density on various type objects caused by distortions of temperature and heat flux field are investigated. Structure of heat flux transducers with improved metrological and operating characteristics is theoretically grounded. Standard measurement tools for reproduction, keeping and transfer of unit size measurement of the heat flux density are developed and principles of hierarchy scheme for means of the heat flux density measuring are grounded. Heat flux transducers and devices to solve various application tasks in wide dynamic range of thermal values were developed, manufactured, certified and implemented in scientific and industrial complex of Ukraine. The system of metrological support and normative documents (standards and measuring techniques) was created to ensure uniformity of measurements heat values and thermal characteristics.
