Project summaryThe project objective is to develop scientific and technical background to improve technical, economical, and ecological performance of pulse MHD generators as well as to promote a methodical base of their use for electromagnetic study of the Earth crust.
The project refers to the field of development and use of high-power pulse energy supplies - magnetohydrodynamic (MHD) generators - for earth crust investigations.
High informativity of Earth crust electromagnetic study makes it possible to solve both fundamental problems of Earth lithospheie structure & evolution and practical problems of great concern: mineral deposits prediction and prospecting, in particular oil and gas; geodynamic and technogenic processes monitoring, etc.
In practice, Earth crust may be electromagnetically studied in two ways: on the base of natural electromagnetic field - yet, its random and non-stationary nature principally restricts accuracy of the results and even range of problems to be solved; and on the base of electromagnetic fields induced artificially by controlled sources.
Progress in electromagnetic methods development and improvement depends immediately on availability of power sources providing high current density and high field intensity. Such effective source is the MHD generator.
In former Soviet Union, a series of large scale geophysical experiments was performed with use of pulse MHD generators initially developed for military applications. The results of these experiments had showed high effectiveness of electromagnetic investigations of Earth crust on the base of such energy sources. Yet, necessity was revealed in improvement of their technical, economical, and ecological performance.
Then, the requirement of the resolving power increase of the electromagnetic sounding gives rise to improvement of methodical principles of the soundings. The project is intended in solving those very problems.
The Project is intended to solve the two of interrelated problems:
Development of linear and disk-type MHD-facilities on gun-powder and powder plasmagenerating fuel with improved technical, economical, and ecological characteristics.
Technology development of the MHD-generators use for geological and geophysical applications.
Within the frame of the project, use will be made of: theoretical and experimental methods of investigation of heterophase supersonic multy-component flows under strong MHD interaction; experimental methods of investigation of the elements of the MHD generators including both physical and technical aspects; numerical simulation and analysis of new sounding and monitoring technologies under model and natural conditions; physical simulation of effect of high-power current pulse on non-uniform media.
The project implementation will give a scientific and methodical background to solving fundamental and applied problems. Within the frame of the project, concept and design will be developed of improved linear- and disc-type MHD generators adapted to geological and geophysical problems. Also, a modern technology and scientific base will be developed of electromagnetic sounding and monitoring providing 3D resolution. A technique and hardware will be created to obtain principally new information on phenomena and processes in the near zone of active electromagnetic impact on non-unifBrm media.
