Abstract

The object of research is the effect of induced heat and mass transfer (IHMT), which consists in the transition of the system from unstable equilibrium to stable, which is accompanied by heat dissipation due to the transition of the liquid phase in the thermostat to the gas state. One of the problematic areas of the research object is the lack of data on the energy efficiency control limits of the induced heat and mass transfer effect by such controlling parameter as the air flow velocity moving relative to the thermostat obturator.

In the course of the research, an experimental technique is used to obtain and analyze the temperature kinetics of a colloidal capillary-porous body inside a thermostat during the IHMT effect. The method of calculating the heat balance is also used. These methods allow to reveal the effect of the air flow velocity relative to the thermostat obturator on the nature of the induced heat and mass transfer.

It is established that the work of the air flow, which moves relative to the obturator, is the controlling parameter by means of which the IHMT «start» is organized. It is determined that the intensity of the induced heat and mass transfer can be regulated within 15...20 % by the velocity of the air flow relative to the thermostat obturators.

It is established that, firstly, it is possible to control the «start» of the IHMT effect in accordance with the goal of technological processing of raw materials using this effect. And secondly, it is reasonable to change the IHMT flow rate and its efficiency by varying the airflow velocity with respect to the obturators.
