  • The possibility of creating and using an integrated complex sensor measuring the temperature and humidity in a greenhouse is considered. The experimental data of temperature measurement by various sensors in the greenhouse and graphs characterizing the operation of the control system of this coordinate according to the readings of the standard sensors are given. Analysis of the data shows the presence of scatter readings, including regular sensors. Based on this, it is concluded that it is expedient to modernize the measurement process. It is proposed to use the dependence of the attenuation coefficient of sound on temperature and humidity to create an integrated complex sensor. The advantages of using the proposed sensor are substantiated. An algorithm for finding the measured values is given. A technique for selecting the frequency of sound vibrations is shown, taking into account the specific conditions of the sensor application. The positive effect is achieved by increasing the information content of the data and the possibility of improving accuracy by increasing the frequency of measurements. The calculations showing the energy and economic efficiency when using the proposed integrated sensor are given.

    Relevance. Vermiculite is one of the representatives of geo-resources that are widely used in various industries. The expanded vermiculite is obtained by heat treating of vermiculite ore concentrates in open flame furnaces. Expanded vermiculite, due to its layered-porous structure and high reflectivity, is the base for obtaining many thermo-insulating and refractory materials and products. Vermiculite is a part of building materials, and it is used to protect against radiation. Heat treating of vermiculite ores in flaming furnaces is an energyintensive process; therefore the designs of electric modular-trigger furnaces are being actively developed. These furnaces have not significantly reduced the specific energy intensity of the firing process, that is why the work on creation of electric furnaces is up-to-date. This research is aimed to develop and construct a furnace prototype of a fundamentally new design. The aim of the research is the experimental determination of operational specifications of a furnace model with a vibrating bottom platform which is a separate single-phase firing module during testing. Methods: analysis of information sources in the field of research, synthesis of constructive solutions, physical modeling, parametric and functional description, experimental studies. Results. The authors have developed the alternative electric furnace for firing vermiculite concentrates with a fundamentally new design structure which is a furnace with a vibrating bottom platform. A full-scale physical model of the furnace unit - a single-phase and single-module unit, was developed. Using the above-mentioned physical model the authors carried out the experiments and obtained the empirical data. During the experimental studies, the density of the expanded vermiculite was 90…91 kg/m3 and the productivity was 3,56 m3/h. The value of volume energy for various types of vermiculite roasting is 63,7…81,6 mJ/m3, which is almost three times less than that of existing open flame furnaces operating on hydrocarbon fuel.

    In this paper, the movement of a gas-fluid flow in a plane channel with an oscillating wall was investigated. The aim of the research is to increase the efficiency of separation equipment by imposing the vibration impact on a gas-liquid flow. This purpose was achieved by applying the phenomenon of selective coagulation of a dropping liquid. The novelty of the proposed approach concerns creating the mathematical model for determination of analytical dependences between the efficiency of the hydromechanical process and initial parameters of the separation device. As a result, quantitatively and qualitatively sufficient approximations for the scalar pressure and vector velocity fields were obtained with a permissible relative error in comparison with the results of numerical simulation. The presence of biharmonic fluctuation of particles was proved; besides, related dependencies for the calculation of vibration characteristics were obtained. Additionally, the paper presents the dependencies for identifying a range of thickness for a near-wall area. The system of dimensionless criteria was proposed for determining flow modes and relative trajectories of liquid droplets in a gas-fluid flow. The numerical simulation approach and related methodology of engineering calculations were proposed on the example of a plane channel of the separation device. Finally, the distance between adjacent zones of the pressure minimum was determined. As a result, it was found that this distance is equal to the wavelength of the vibrating impact to the flow that is an initial justification of further coagulation process of liquid droplets in a gas-liquid flow in a separation device.

    In this paper, the movement of a gas-fluid flow in a plane channel with an oscillating wall was investigated. The aim of the research is to increase the efficiency of separation equipment by imposing the vibration impact on a gas-liquid flow. This purpose was achieved by applying the phenomenon of selective coagulation of a dropping liquid. The novelty of the proposed approach concerns creating the mathematical model for determination of analytical dependences between the efficiency of the hydromechanical process and initial parameters of the separation device. As a result, quantitatively and qualitatively sufficient approximations for the scalar pressure and vector velocity fields were obtained with a permissible relative error in comparison with the results of numerical simulation. The presence of biharmonic fluctuation of particles was proved; besides, related dependencies for the calculation of vibration characteristics were obtained. Additionally, the paper presents the dependencies for identifying a range of thickness for a near-wall area. The system of dimensionless criteria was proposed for determining flow modes and relative trajectories of liquid droplets in a gas-fluid flow. The numerical simulation approach and related methodology of engineering calculations were proposed on the example of a plane channel of the separation device. Finally, the distance between adjacent zones of the pressure minimum was determined. As a result, it was found that this distance is equal to the wavelength of the vibrating impact to the flow that is an initial justification of further coagulation process of liquid droplets in a gas-liquid flow in a separation device.
