Спроектовано спеціалізовану систему з мікропроцесорним обробленням сигналу на базі перепрограмованої системи на кристалі PSoC для контролю таких параметрів середовища, як температура та відносна вологість з використанням розроблених наноструктурованих давачів. Розроблено базу даних для реєстрації, зберігання та аналізу параметрів стану довкілля.
Mathematical modelling of heat exchange processes for an electric device of inhomogeneous structure and the analytical numerical estimate of the relevant boundary problem of heat conduction have been considered.
Are ways electrical frictional cutting billets by friction circular saws. The features of thermal phenomena in the processing and developed a mathematical model for calculating the contact temperature in the cutting zone, which takes into account complex thermo-physical conditions and modes of processing, thereby allowing control of processes of heat generation and the quality of the machined surface.
This paper deals with the accuracy of gas flow temperature measurement in natural gas metering systems. The effect of heat exchange between thermometer well and the pipe wall on the accuracy of gas flow temperature measurement is investigated. A mathematical model is proposed to calculate the additional systematic error of gas flow temperature measurement caused by heat exchange between thermometer well and the pipe wall. Calculation results were compared to the corresponding experimental values of this error.
