Abstract
The purpose of this article is to increase the efficiency of the design process and reduce the cost of field experiments by using numerical analysis methods of the dimensional capacity heating efficiency of the internal combustion engine exhaust system. To solve the problem, a non-stationary nonlinear solver of gas dynamic processes (Siemens STAR-CCM+) was used, which allows to evaluate the correctness of the problem statement, significantly reducing the cost of full-scale tests. The paper considers the heating of a dimensional two-section tank in the layout of the cementing unit on the chassis with a triplex high-pressure pump and a drive from the power take-off box on the gear box of the chassis engine. The exhaust pipe structurally passes inside the measuring tank. According to the research results obtained graphic dependences of temperature change of liquid measuring cups to control points, the distribution of temperature field of the liquid in a volumetric tank, distribution of the temperature field of the surrounding air, stream lines and velocity field of the ambient air and the exhaust gases of internal combustion engines. The results of the calculations clearly show that the application of the method of heating the measuring capacity by entering the exhaust pipe directly into the liquid can be considered effective.
Highlights
With the increasing rates of oil and gas-bearing territories development of the Northern and Arctic latitudes of the country, where hydrocarbon reserves are difficult to recover, oil composition is heavy and viscous with accompanying fatty gases, ensuring a guaranteed plus temperature of the process fluid in the process of drilling and overhaul of wells is one of the priorities in the development of equipment for this work [1,2,3]

Summary
With the increasing rates of oil and gas-bearing territories development of the Northern and Arctic latitudes of the country, where hydrocarbon reserves are difficult to recover, oil composition is heavy and viscous with accompanying fatty gases, ensuring a guaranteed plus temperature of the process fluid in the process of drilling and overhaul of wells is one of the priorities in the development of equipment for this work [1,2,3]. The use of water treatment heating systems is impossible in the conditions of territorial separation of wells and their inaccessibility, in connection with which, today, mobile Autonomous liquid heating systems for oil and gas fields are still relevant. One variant of such systems is the use of hot exhaust gases of chassis engines or deck internal combustion engines of pumping units to heat the liquid in measuring tanks. The use of internal combustion engine exhaust gases for heating the equipment used in modern pumping units, and the task of studying the effectiveness of such systems is relevant
