Engineering Physics Annotation << Back UNSTATIONARY HEAT EXCHANGE IN MINING HOLE AT HEATING OF LIQUID DEVICE A.SH. RAMAZANOV, V.M. NAGIMOV Given article describes mathematical model non-stationary heat exchange between a heater and a washing liquid. At calculations the method of Laplace’s transformation is used. The decision of the given problem allows to estimate duration of transient during which the stationary mode of heat exchange is established. Estimated optimum sizes of heater. Results of a problem can be using in thermometry of an artificial thermal stream by system consideration from a heater and the temperature sensor. Keywords: non-stationary heat exchange, artificial thermal field, thermometry, chink, heat exchange factor. E-mail: nagwinmor@mail.ru
