Applied Physics and Mathematics Annotation << Back STUDY OF EMITTER CHARACTERISTICS ON THE BASIS OF HELMHOLTZ RESONATOR IN A FLUID FLOW R.N. GATAULLIN, J.I. KRAVTSOV, E.A. MARFIN This article is devoted the solution of some scientifi c and practical problems of increasing the eff ectiveness technology of combined action on oil reservoirs and optimizing the design of pressure oscillators that underlines its urgency. The mathematical model is introduced, allowing to spot dependence of Strouhal number on geometrical performances of the Helmholtz resonator which is a basic element of an emitter. In work are also introduced results of an experimental research of an emitter and tendered optimum geometrical parameters of the device for the purpose to increase the eff ectiveness of oscillation. Keywords: an emitter of oscillations, a Helmholtz resonator, wave action, Strouhal number, the combined action, oil recovery. Contacts: E-mail: rustem.acadrome@mail.ru Pp. 03-11.
