THE CONDENSATION OF WATER VAPOUR IN A MIXTURE CONTAINING A HIGH CONCENTRATION OF NON-CONDENSABLE GAS IN A VERTICAL TUBE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)This paper deals with the condensation of water vapour possessing a content of noncondensable gas in vertical tubes. The condensation of pure steam on a vertical surface is introduced by the Nusselt condensation model. ... -
THE DEVELOPMENT OF A NEW ADSORPTION-DESORPTION DEVICE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)The aim of this work was to construct a new adsorption-desorption device based on the principle of separation of volatile organic compounds, e.g., ethanol. As an adsorbent, it is possible to use granulated activated carbon ... -
THE EFFECT OF THE FILLING RATIO ON THE OPERATING CHARACTERISTICS OF AN INDIRECT DRUM DRYER
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)This article investigates the effect of the filling ratio of the indirect rotary dryers on their operating characteristics.
