The article is devoted to modeling heating of fuel oil using a pulsed fluid flow in the SolidWorks Flow Simulation software module. In the future, the use of this technological solution can be considered by a number of industries in the Russian Federation and abroad. The purpose of this article is to describe the results of a computer model of the technological process under study. The computer calculation of the fuel oil heating model using a pulse flow makes it possible to evaluate the efficiency of the process and determine the optimal parameters to achieve maximum efficiency. This will help to reduce the cost of heating fuel oil and increase the efficiency of industrial equipment of enterprises.

The object of the development is an experimental installation with pulsed circulation of the coolant in the main circuit for its use as a hydraulic drive of a diaphragm pump used for pumping liquid in the secondary circuit, which increases the energy efficiency of the pump drive for small-scale energy facilities. An installation with pulsed circulation of the coolant with a diaphragm pump was developed, assembled and tested on the basis of a new design of the shock unit with a cam profile, which makes it possible to create an acceleration of the flow at the pump suction. As a result of the experiment, we obtained the dependence of the volume of the pumped liquid on the frequency of operation of the shock unit.
