The simultaneous presence of several different fluids in external or internal flows is found in daily life, environment and numerous industrial processes. These types of flows are termed multi-fluid flows. Examples are gas-liquid transport, crude oil recovery, spray cans, sediment transport in rivers, pollutant transport in the atmosphere, cloud formation, fuel injection in engines, bubble column reactors and spray driers for food processing, to name only a few. Real time computational mechanics (RTCM) aims to developing computational systems to solve problems which must produce their results within short time intervals. Examples of real-time systems include flight control programs, patient monitoring; nuclear plants controls, industrial processing and prevention of risk. RTCM systems are having an ever increasing impact on the quality of human life. The objective of the project is to develop new formal approaches and computational methods based on innovative RTCM procedures for building accurate and robust quasi-real time computer codes applicable to solve multi-fluid engineering problems. In the project we will develop and validate new computational fluid dynamic techniques based on innovative particle methods, new time integration schemes allowing large time steps, reduction methods, GPUs and parallel processing to reach acceptable results for multi-fluid problems in quasi-real time. The main outcome of the REALTIME project will be a collection of methods and codes to predict and control in quasi-real time different problems involving natural and human induced hazards such as risky industrial processes, fire spread, critical atmospheric situations or patients monitoring situations in which the security or human life depends of a response in real time.
