Changes in the world order, political and economic events of modern times reveal relevant aspects for the development of financial instruments. The interest shown in microfinance organizations is determined by the socio-economic realities of the country: the urgent need to revive entrepreneurship, internal competition, adaptation to the market in a limited economy. In this connection, the considered conceptual provisions are aimed at prompt response to deviations from the normal activities of entrepreneurship. There was a need for changes in international and national investment policy on the way to a real network development methodology: from a coordinated structure of relations to more and more legally binding decisions of all participating countries. Investments are dispersed. In this regard, the development of methodological aspects, the design of a roadmap, taking into account recommendations for the formation of an operating model and a business model within the framework of MFO activities, seems to be very relevant.

The main purpose of this work is to simulate a dynamics of DC discharge in a subsonic airflow. The calculations were performed in the FlowVision 3.12.01 software package. The single-fluid model (MHD approach) of equilibrium plasma was used while the initial discharge channel was set manually. Cylindrical coaxially arranged electrodes were located in the central part of the calculation area, in the core of the airflow. A 5A DC discharge at atmospheric pressure was considered, as well as a simple model of a re-breakdown between parts of discharge filament. In this work, three-dimensional distributions of temperature and current density were obtained during an evolution of discharge in a flow. Discharge channel extension by the airflow and partial channel decay after the re-breakdown process were shown.
