INNOVATIVE TECHNOLOGY, ATTENUATION OF HEAT AND GAS FLOWS

The proposed article introduces a new innovative technology, developed by the Uzbek and Russian experts, allowing weakening the heat flow in ten times. The design of a heat shield “Sogda” consists of two parallel metallic grids stretched over metallic frames. A special water spray nozzles located between two parallel fixed grids provides the power to weaken the thermal heat flux. Activated water discharge in the system creates water film on the surface of grids and water vapour droplet-air environment in the space between two parallel grids. This complex is partially absorbs heat flow, reflecting electromagnetic waves, mainly in infrared range, preventing the passage of gases. The attenuation of the thermal heat flux in ten times is achieved through the thermophysical effects as well as optical phenomena. The article also describes experimental studies the performance of screen, and theoretical studies of the process of absorption, reflection, and weakening heat flows by heat shield. The method to reduce heat flow and the thermal protective screen “Sogda” is patented in Russia, Uzbekistan, England, France, Germany, China, USA, and other countries. The screens have been successfully brought in to operation in Russia and Uzbekistan in extinguishing the complex fires
