Industrial Automatic Control Systems and Controllers Annotation << Back Investigation of Temperature Changes During Filtration of Abnormal Liquid by Khusainovа G.Y. The filtration of abnormal fluid in steadystate fl ow is considered. Since in the conditions of real reservoir systems, the establishment of the pressure fi eld occurs much faster than the temperature fi eld. The analytical solution and graphs for the planeparallel flow are obtained and the analysis is carried out. The solution of the equation is obtained by the method of characteristics. The analysis of the results showed that the temperature in the fl uid fl ow for a rectilinearly parallel fl ow varies at short distances according to a linear law and at long distances does not depend on it, but depends only on time. When fi ltering an abnormal liquid, the thermal heating of the reservoir is greater than when filtering a Newtonian liquid. At low fl ow rates, the dependence of the relative temperature increase on the initial shift gradient is signifi cant, and with an increase in fl ow rate, the temperature dependence on the initial gradient decreases. Keywords: abnormal liquid, filtration, temperature fields, pressure fields, initial pressure gradient. DOI: 10.25791/asu.2.2025.1565 Pp. 39-43.
