The features of determining the main hydrodynamic parameters of the process of soil electrokinetic treatment are considered. The main problem in determining these parameters is the complexity of the research and the necessity to use special laboratory equipment. One of the ways to solve this problem is proposed to use computer simulation of physical processes occurring in clay soils subjected to electroosmotic and electrochemical (ECP) processing. The results of calculations of the hydrodynamic parameters of the process of soils electrochemical treatment carried out according to the developed methodology of experimental- analytical assessment of the clay soils electrical and hydrodynamic parameters according to the results of physical and computer modeling of processes in the area of electroosmotic processing are presented. The results of comparing hydrodynamic parameters calculated by computer simulation of unsteady physical processes occurring in clay soils during their electroosmotic and electrochemical processing are presented.

The article discusses contextual technology of teaching and learning physics of IT students at the Technical University. The main goal of this research is development and analysis contextual technology to maintain and increase IT students’ interest in physics with parallel formation of computational thinking and competencies in computer science applications. This technology takes place in several contexts: the scientific method and modeling of physical processes, computational thinking and professional competence. The all contexts are present in four stages of the training cycle: lectures, seminars, lab works, and computer modeling of physical processes. As an example we demonstrate using the contextual technology for the physics course topic “Dynamics of a rigid body rotational motion” in all four stages of the training cycle. The example of student’s team development of the virtual lab work “Precession and nutation of a gyroscope” is given. According to the Novosibirsk State Technical University professors and students, the author’s technology has demonstrated its effectiveness in the formation of professional thinking and competencies of the IT students in teaching physics at the Technical University.

Interelectrode Gap

The features of the hydrodynamics of the electrolyte in the interelectrode gap during electrochemical processing of a profile axisymmetric workpiece are considered. The distribution of average flow rates and flow lines is calculated for a specified electrolyte supply. The nature and rate of the electrolyte flow are established. The unevenness of the current density is determined taking into account the change in the electrical conductivity of the electrolyte from heating and gas filling of the interelectrode gap, as well as the quality of the treated surface. Keywords: electrochemical treatment, roughness, electrolyte, electrical conductivity, gas filling. [email protected]

The article seeks to examine the efficiency of applying means of mathematical processing and computer modeling of the work processes of gas cleaning facilities of power plants to optimize the process of planning and designing of future power plant in operation. A way of solution of the gas outbursts cleaning problem at the stage of designing measures for the development of waste processing systems through mathematical processing of expected volumes of gas outbursts and computer simulation of individual pieces of equipment and working areas as a whole is offered. The authors present the results of the processing of the projected technological processes and the gas outbursts cleaning facilities in terms of E-networks and using mathematical processing in the application Simulink, which allows to build a model of the device and to carry out calculations on the screen using the library of building blocks. A 3D model of the gas cleaning facilities, which allows to visualize the technological process and to compare it with theoretical calculations at the design stage of the future power plant and, if necessary, make changes to the project, has been created by means of computer modeling.

AbstractComputer modeling of fluids in zeolites can provide a detailed molecular level understanding of the process of adsorption and diffusion under the influence of the 3-D potential field and the confinement offered by the crystal structure. We have shown that there is a strong link between the location, geometry and energetics of sites and the observed thermodynamics and spectroscopy of the adsorbates. Here we report on the modeling of Xe in zeolite Y, which is of interest both because it is commercially important and because it offers two distinct adsorption sites.

Electrochemical Removal

<p>The removal of mercury from soil and Ca-bentonite was performed using electrochemical treatment adding ethylendiaminetetra acetic acid (EDTA) as a complexing agent to improve the electrochemical removal of Hg (II) in soil from San Joaquín, Querétaro, México. During the electrokinetic treatment in the presence of 0.1 M EDTA, most of Hg (II) migrates toward the anode obtaining the highest removal efficiencies close to 70 % in bentonite after 9 h. Using 0.1M HCl only 65 % efficiency was attained after 13 h in the cathodic side. EDTA formed a negatively charged stable complex that migrates to the cathode by the application of the electrokinetic treatment across Hg – EDTA synthesized complex.</p>
