Our department has been dealing with the flow, chemical and biological phenomena occurring in pipe networks (drinking water supply systems, sewage networks, air and natural gas networks) for several decades. Out of these, hydraulic modeling of water networks (in steady and transient states), leak detection, solving optimization and sensor placement problems, estimating chlorine concentration distribution, predicting biological activity, the flow of compressible media (air, natural gas, hydrogen) and the operation of fluid machinery (pumps, compressors, fans) have received special attention during research.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
