Environmental Fluid Mechanics (EFM)
This research division is aimed at fluid flow and associated heat and mass transport processes that arise in different types of water bodies (river, lakes, resevoirs, coastal water) covering local and regional scales. The interaction of these flow processes with engineering structures and devices is the first major focus of these studies. The second focus is on their response to anthropogenic heat and mass sources with regard to water quality aspects. Examples of current research projects that utilize a combination of analytical, numerical and experimental methods are:
This research division is concerned with hydraulic and fluid mechanical problems that guarantee technically safe and environmentally acceptable design and operation of hydraulic structures and systems. Physical model studies, as well as analytical and numerical methods are utilized to arrive at innovative design solutions.
- Design of flow control structures such as weirs, sluice gates, inlet and other structues.
- Evaluation of hydrodynamic loads on steel control devices, including design safety.
- Computation of open channel flow and backwater curves (e.g. numerical program HEC-RAS).
- Studies on channel bed stability and design of energy dissipation structures.
- Investigation of closed conduit and pipe flow systems, including local energy losses for special geometries, pipe network design.
