“…Despite the signifi cant ups and downs in the modeling and understanding of the effect], practical applications follow their course [01,13]. In our previous work, we discussed the features of the application of a particular construction [14][15][16][17] constructed with the aim of using the separation capabilities of the Ranque-Hilsh effect. Further discussion of our design led to an understanding of the independence of research on the physics of processes and the practice of constructing serial production.…”

Vortex motion is effectively used in the development of wellbore fi lter designs. Further development of the principles of such design requires the development of some principles based on experimental observations and computer modeling. A constructive analogy between the wellbore fi lter and the Ranque vortex tube is shown. The results of experimental and theoretical studies of the vortex tube are applied as a basis for designing a well separator. Recommendations are formulated regarding the radius of the inner branch pipe of the downhole fi lter placed in the body. Approaches are discussed when choosing the length of the working section of the well separator, as well as the choice of the shape of the input cochlear, the size of the outlet diaphragm, and the shape of the sand suspension window.
